What will be the output? 
public class Test{
      public static void main(String args[]){
            int a = 42;
            double b = 42.25;
            System.out.print((a%10)+" "+(b%10));
      }
}

  • A 42 42.5
  • B 2 2.5
  • C 4.2 4.225
  • D 2 4.225

what will be the output? 
public class Test{

      public static void main(String args[]){

            System.out.print(""=="");

            System.out.print(" ");

            System.out.print("A"=="A");

            System.out.print(" ");

            System.out.print("a==A");

      }

}

  • D Compilation Fails

What will be the output for the below code? 
class Test{
        public void display(int x, double y){
                System.out.println(x+y);
        } 
        public double display(int p, double q){
                return (p+q);
        }
        public static void main(String args[]){
                Test test = new Test();
                test.display(4, 5.0);
                System.out.println(test.display(4, 5.0));
        }
}

  • A 9.0 9.0
  • B 9 9
  • C Compilation Error
  • D None of these

Which of the following is the correct expression that evaluates to true if the number x is between 1 and 100 or the number is negative?
  • A 1 < x < 100 || x < 0
  • B ((x < 100) && (x > 1)) || (x < 0)
  • C ((x < 100) && (x > 1)) && (x < 0)
  • D (1 > x > 100) || (x < 0)

What will be the value of "x" after execution ? 
int x = 0, y = 0 , z = 0 ;
x = (++x + y-- ) * z++;

  • A -2
  • B -1
  • C 0
  • D 1

Determine output: 
public class Test{
      public static void main(String... args){
            int a=5 , b=6, c=7;
            System.out.println("Value is "+ b + c);
            System.out.println(a + b + c);
            System.out.println("String " + (b+c));
      }
}

  • A Value is 67 18 String 13
  • B Value is 13 18 String 13
  • C Value is 13 18 String
  • D Compilation fails

Determine output: 

public class Test{
      static int i = 5;
      public static void main(String... args){
            System.out.println(i++);
            System.out.println(i);
            System.out.println(++i);
            System.out.println(++i+i++);
      }
}

  • A 6 6 6 16
  • B 6 7 6 16
  • C 5 6 7 16
  • D 5 6 6 16

What will be the output? 
if(1 + 1 + 1 + 1 + 1 == 5){
        System.out.print("TRUE");
}
else{
        System.out.print("FLASE");
}

  • A TRUE
  • B FALSE
  • C Compiler Error
  • D None of these 

int ++a = 100 ; 
System.out.println( ++a ) ;
What will be the output of the above fraction of code ?
  • A 100
  • B Displays error as ++a is not enclosed in double quotes in println statement
  • C Compiler displays error as ++a is not a valid identifier
  • D None of these
