How to swap two string variables in Java without using a third variable

Question

How do I swap two string variables in Java without using a third variable, i.e. the temp variable?

String a = \"one\"
String b = \"two\"
String temp = null;
temp         


        

Answer 1

• Actually, the code in your question did not swap String a,b.

  You should see this issue: Swap two strings in Java, by passing them to a utility function, but without returning objects or using wrapper classes

• And Java is passing by value: Is Java "pass-by-reference" or "pass-by-value"?
