        arr[0] = 23; 
        arr[1] = 9; 
        arr[2] = 983; 
                
        return arr; 
    } 
    public static void main(String args[]) {
        int[] result =  m(); 
          
        System.out.println(result[0]);
        System.out.println(result[1]);
        System.out.println(result[2]);

final class Test
{
    public String s;
    public int i;
    public char ch;
 
    public Test(String s, int i, char ch) {
        this.s = s;
        this.i = i;
        this.ch = ch;
    }
}
 
public class MyClass
{
    public static Test getDetails() {
        String s = "Java";
        int i = 84672;
        char ch = 'z';
 
        return new Test(s, i, ch);
    }
 
    public static void main(String[] args)
    {
        Test test = getDetails();
 
        System.out.println(test.s);
        System.out.println(test.i);
        System.out.println(test.ch);
    }
