ToString Java array

I have several arrays in a class

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

What should I do?

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;
    }

This prints all VAR1 [] contents, but how do I print all? Do I have to circle a circle for everyone?

Solution

You can use arrays Tostring() static helper method is as follows:

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