toString java of arrays

Question

I have several arrays in a class

I want to implement toString() to print all values.

How to do this?

public String var1[];   
public int var2         


        

Answer 1

String someArray = new String[] {"1", "2"};
String toString = Arrays.asList(someArray).toString();

The code above will print out the toString in a more readable format:

[1, 2]

If you are using JDK 1.5, you can use:

String[] strings = { "ABC", "DEF" };
String s = Arrays.toString(strings);
