Java Operators

Which statement(s) are equivalent to i = i + 1?

• i += 1

• i++

• i -= 1

• i--

++ increases the value of a variable by 1

• assignment operator

• decrement operator

• increment operator

• sentinel

What's the value of below?

int i=5;

System.out.println(i++);

System.out.println(i);

System.out.println(++i);

• 5

  6

  7

What would the new value of A be?

A=1;

a++;

• 1

• 2

• 3

• 4

Please write correct output in following space-

• 10

• 20

• No Output

• Error

Find the output for the following.

public class IncDec

{

public static void main(String s[])

{

int a = 1;

int b = 2;

int c;

int d;

c = ++b;

d = a++;

c++;

System.out.println("a = " + a);

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

System.out.println("c = " + c);

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

}

}

• a = 2 b = 3 c = 4 d = 1

• a = 2 b = 3 c = 4 d = 1

• Program does not compile.

• a = 1 b = 2 c = 4 d = 2

What will be the output of the program?

class Test

{

public static void main(String [] args)

{

int x=20;

String sup = (x < 15) ? "small" : (x < 22)? "tiny" : "huge";

System.out.println(sup);

}

}

• small

• tiny

• huge

• Compilation fails

Find the output of the following snippet.

class Numbers

{

public static void main(String args[])

{

int a=20, b=10;

if((a<b)&&(b++ <25))

{

System.out.println("this is any language logic");

}

System.out.println(b);

}

}
