What will be the output of running class Test?

Select 1 correct option

class Test 
{
   public static void main(String[] args) 
   {
      int d = 0;
      try 
      {
         int i = 1 / (d* doIt());
      } catch (Exception e)
      {
         System.out.println(e);
      }
   }

   public static int doIt() throws Exception 
   {
      throw new Exception("Forget It");
   }
}

public class TestClass 
{
   public static void main(String args[ ] ) 
   {
      A o1 = new C( );
      B o2 = (B) o1;
      System.out.println(o1.m1( ) );
      System.out.println(o2.i );
   }
}


class A
{
    int i = 10;
    int m1( ) {
        return i;
    }
}


class B extends A
{
    int i = 20;
    int m1() {
        return i;
    }
}


class C extends B {
    int i = 30;
    int m1() {
        return i;
    }
}

String str1 = "one";
String str2 = "two";
System.out.println( str1.equals(str1=str2) );

class TestClass
{
   int i;
   public TestClass(int i) { this.i = i;  }
   public String toString()
   {
       if(i == 0) return null;
       else return ""+i;
   }

   public static void main(String[ ] args)
   {
      TestClass t1 = new TestClass(0);
      TestClass t2 = new TestClass(2); 
      System.out.println(t2);
      System.out.println(""+t1);
   }
}

boolean b1 = false;
boolean b2 = false;
if (b2 != b1 = !b2) 
{
   System.out.println("true");
}
else 
{
   System.out.println("false");
}

class TechnoSample {
    public static void main(String[] args) {
        double d1 = 1.0;
        double d2 = 0.0;
        byte b =1;

        d1 = d1/d2;
        b = (byte) d1;
        System.out.print(b);
    }
}

Class finalization can be done by implementing the following method:
static void classFinalize() throws Throwable;

True Or False?

public void getLocks(Object a, Object b)
{ 
  synchronized(a)
  { 
    synchronized(b) 
    { 
      //do something 
    } 
  } 
}

and the following instantiations:


Object obj1 = new Object(); 
Object obj2 = new Object();


obj1 and obj2 are accesible to two different threads and the threads are about to call the getLocks() method.

Assume the first thread calls the method getLocks(obj1, obj2).


Which of the following is true? 

package com.technopark;
    
public class TestClass 
{
   int i;
   public int j;
   protected int k;
   private int l;
}

Will the following code compile ? If yes , what is the output ?

class sample {

		sample(int i){
			System.out.println(i);
			this.i = i;

		}

		public static void main(String args[]){
			sample object = new sample(10);
		}
}
