I just got the program for home to try to finish off a lab I was working on and when I compile, this shows up: ----jGRASP exec: javac -g EqualToThree.java ----jGRASP wedge2 error: command "javac" not found. ---- This command must be in the current working directory or ---- on the current system PATH or jGRASP PATH to use this function. ---- System + jGRASP PATH is "C:\Program Files\Java;C:\WINDOWS\system32;C:\WINDOWS\system32\wbem;C:\Program Files\QuickTime\QTSystem;C:\Documents and Settings\Andrew\My Documents\Downloads;C:\WINDOWS\system32;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\QuickTime\QTSystem\". ---- Use Settings > PATH/CLASSPATH > Workspace (PATHS tab) ---- to add directories to the jGRASP PATH. ----jGRASP: operation complete. I just recently upgraded my java to the latest version, and I honestly have no idea how to fix this. I did go to the class path, and selected the selected files it wants, but still no luck. Any idea? java compiler-construction jgrasp share|improve this question asked Feb 11 '14 at 23:12 MTNLegit 914 Did you actually install the JDK? –
Common Problems (and Their Solutions) Compiler Problems Common Error Messages on Microsoft Windows Systems 'javac' is not recognized as an internal or external command, operable program or batch file If you receive this error, Windows wedge error: command "javac" not found cannot find the compiler (javac). Here's one way to tell Windows where to find jgrasp g++ not found javac. Suppose you installed the JDK in C:\jdk1.8.0. At the prompt you would type the following command and press Enter: C:\jdk1.8.0\bin\javac jgrasp jdk HelloWorldApp.java If you choose this option, you'll have to precede your javac and java commands with C:\jdk1.8.0\bin\ each time you compile or run a program. To avoid this extra typing, consult the section Updating http://stackoverflow.com/questions/21715216/how-to-fix-the-compiler-error-in-this-program the PATH variable in the JDK 8 installation instructions. Class names, 'HelloWorldApp', are only accepted if annotation processing is explicitly requested If you receive this error, you forgot to include the .java suffix when compiling the program. Remember, the command is javac HelloWorldApp.java not javac HelloWorldApp. Common Error Messages on UNIX Systems javac: Command not found If you receive this error, UNIX cannot find the compiler, javac. Here's https://docs.oracle.com/javase/tutorial/getStarted/problems/ one way to tell UNIX where to find javac. Suppose you installed the JDK in /usr/local/jdk1.8.0. At the prompt you would type the following command and press Return: /usr/local/jdk1.8.0/javac HelloWorldApp.java Note: If you choose this option, each time you compile or run a program, you'll have to precede your javac and java commands with /usr/local/jdk1.8.0/. To avoid this extra typing, you could add this information to your PATH variable. The steps for doing so will vary depending on which shell you are currently running. Class names, 'HelloWorldApp', are only accepted if annotation processing is explicitly requested If you receive this error, you forgot to include the .java suffix when compiling the program. Remember, the command is javac HelloWorldApp.java not javac HelloWorldApp. Syntax Errors (All Platforms) If you mistype part of a program, the compiler may issue a syntax error. The message usually displays the type of the error, the line number where the error was detected, the code on that line, and the position of the error within the code. Here's an error caused by omitting a semicolon (;) at the end of a statement: testing.java:14: `;' expected.

General Information The PATH is https://www.java.com/en/download/help/path.xml the system variable that your operating system uses to locate needed executables from the command line or Terminal window. The PATH system variable can be set using http://introcs.cs.princeton.edu/15inout/windows-cmd.html System Utility in control panel on Windows, or in your shell's startup file on Linux and Solaris. Making changes to the system PATH variable is typically not not found necessary for computers running Windows or Mac OS X. Windows Windows 10 and Windows 8 In Search, search for and then select: System (Control Panel) Click the Advanced system settings link. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does wedge error: command not exist, click New. In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. Click OK. Close all remaining windows by clicking OK.

Java You will use the Java compiler javac to compile your Java programs and the Java interpreter java to run them. You should skip the first step if Java is already installed on your machine. Download and install the latest version of the Java Platform, Standard Edition Development Kit (Java SE 6 Update 27). Note the installation directory for later—probably something like C:\Program Files\Java\jdk1.6.0_27\bin. To make sure that Windows can find the Java compiler and interpreter: Select Start -> Computer -> System Properties -> Advanced system settings -> Environment Variables -> System variables -> PATH. [ In Vista, select Start -> My Computer -> Properties -> Advanced -> Environment Variables -> System variables -> PATH. ] [ In Windows XP, Select Start -> Control Panel -> System -> Advanced -> Environment Variables -> System variables -> PATH. ] Prepend C:\Program Files\Java\jdk1.6.0_27\bin; to the beginning of the PATH variable. Click OK three times. Command-line interface You will type commands in an application called the Command Prompt. Launch the command prompt via All Programs -> Accessories -> Command Prompt. (If you already had a command prompt window open, close it and launch a new one.) You should see the command prompt; it will look something like: Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved. To check that you have the right version of Java installed, type the text in boldface below. You should see something similar to the information printed below. (It's important that you see the number 1.6 or 1.5 for the Java version number, but the rest is not critical.) C:\Users\username>java -version java version "1.6.0_27" Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0_27-b07) Java HotSpot(TM) Client VM (build 1.6.0_27-b13, mixed mode, sharing) Then type: C:\Users\username>javac -version javac 1.6.0_27 Since you will be using the Command Prompt frequently, we recommend customizing the default settings. Right-click the title bar of an open Command Prompt window, select Properties and then: Set Layout -> Screen Buffer Size to 80 x 500. Select Options -> Edit Options -> QuickEdit Mode. Select Options -> Edit Options -> Insert Mode. Compile the Program You will use the javac command to convert your Java program into a form more amenable for execution on a computer. From the Command Prompt, navigate to the directory containing your .java files, say C:\introcs\hello, by typing the cd command below. C:\Users\username>cd c:\introcs\hell
