The commented out variables are double and do not work. @Override public String toString() { return "[" + getAccountNumber() + "], " + super.toString() + ", " + owner.toString() // Error: "Double Cannot be Dereferenced" why? // + ", " + currentBalance.toString() // + ", " + compareto double java interestRate.toString() ; } When I rewrite it like this NetBeans doesn't give me an error, but is this effectively the same thing for a double? @Override public String toString() { return "[" + getAccountNumber() + "], " + super.toString() + ", " + owner.toString() // Error: "Double Cannot be Dereferenced" // + ", " + currentBalance.toString() // + ", " + interestRate.toString() // The following seems to work instead: + ", " + Double.toString(currentBalance) + ", " + Double.toString(interestRate) ; } If so, great. No errors. If not, what can I do to make sure that the value of a double returns to the String just as an int would? UPDATE: From the answers I received, it looks like second approach I used works, but the following works just as well: @Override public String toString() { return "[" + getAccountNumber() + "], " + super.toString() + ", " + owner + ", " + currentBalance + ", " + interestRate; } java netbeans return double tostring share|improve this question edited Sep 23 '15 at 14:48 asked Sep 23 '15 at 14:09 Elliander 107111 1 Try String.valueOf(your_double_variable) and same in opposite-direction Double.valueOf(your_String_variable).
