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[];
public String var3[][];
public int var4[];
public int var5[][];

public String toString() {

        for(String s :  var1) {
              System.out.println(s.toString());           
        }


        return  null;
    }

That prints all var1[] content but how to print all?? Do I have to put a loop for every one of them?

Answer 1

You can use the Arrays.toString() static helper method as follows:

String lines[] = getInputArray();
System.out.println(java.util.Arrays.toString(lines));

Answer 2

I think what you are looking for is Arrays.deepToString()

Refer to this link for more details. It takes an array and calls toString() on every element.
