In the given program, how many lines of output will be produced?

public class Test 
{
    public static void main(String [] args) 
    {
    int [] [] [] x = new int [3] [] [];
    int i, j;
    x[0] = new int[4][];
    x[1] = new int[2][];
    x[2] = new int[5][];
    for (i = 0; i < x.length; i++)
    {
        for (j = 0; j < x[i].length; j++) 
        {
            x[i][j] = new int [i + j + 1];
            System.out.println("size = " + x[i][j].length);
        }
    }
    }
}

What will be the output of the program?

public class X 
{
    public static void main(String [] args) 
    {
        String names [] = new String[5];
        for (int x=0; x < args.length; x++)
            names[x] = args[x];
        System.out.println(names[2]);
    }
}

and the command line invocation is

> java X a b

You want subclasses in any package to have access to members of a superclass. Which is the most restrictive access that accomplishes this objective?

public class Outer 
{ 
    public void someOuterMethod() 
    {
        //Line 5 
    } 
    public class Inner { } 
    
    public static void main(String[] argv) 
    {
        Outer ot = new Outer(); 
        //Line 10
    } 
} 

Which of the following code fragments inserted, will allow to compile?

interface Base 
{
    boolean m1 ();
    byte m2(short s);
}

which two code fragments will compile?

1. interface Base2 implements Base {}
2. abstract class Class2 extends Base
   { public boolean m1(){ return true; }}
3. abstract class Class2 implements Base {}
4. abstract class Class2 implements Base
   { public boolean m1(){ return (7 > 4); }}
5. abstract class Class2 implements Base
   { protected boolean m1(){ return (5 > 7) }}
