Predict the output of the following Java code.

Which of these code segments will give an error for declaration of a char variable in Java?

What is the type of variable ‘b’ and ‘d’ in the following Java snippet?

int a[], b;
int []c, d;

Which two cause a compiler error?

1. float[ ] f = new float(3);
2. float f2[ ] = new float[ ];
3. float[ ]f1 = new float[3];
4. float f3[ ] = new float[3];
5. float f5[ ] = {1.0f, 2.0f, 2.0f};

public class outputs 

    {

        public static void main(String args[]) 

        {

          int a = 3;

 int b = 12;

             System.out.print(++a%10 * 8%2 + ++a%b);

        } 

    }

public class output{

public static void main(String args[]){ 

char num [] = new char[10];

for (int i = 0; i < 10; ++i){

num[i] = 'S';

System.out.print(num[i] + "");

 }

}

} 

What will be the output of the following Java program?

class Output

{

public static void main(String args[])

{

Double i = new Double(257.5);

Double x = Double.MIN_VALUE;

System.out.print(x);

}

}

class A

    {

        public static void main(String args[])

        {

            int a= 15; 

            int b= 20;

            if ((b = 1) == a)

                System.out.print(b);

            else 

                System.out.print(++b);

        } 

    }

Is it possible to use a default constructor even if an explicit constructor is defined?

 class show 

    {

        public static void main(String args[])

        {

            try 

            {

                throw new NullPointerException ("Hello");

                System.out.println("Abekus");

            }

            catch(ArithmeticException e) 

            {

         System.out.println("Slack");        

            }

        }

    }
