3 Bitwise Right Shift Operations:
• The program performs both right shift (>>) and unsigned right shift (>>>) operations on both positive and
negative numbers.
4 Examples:
• System.out.println(20 >> 2);
• Right shift the binary representation of 20 by 2 positions using the >> operator.
• After right shifting by 2, 20 becomes 5 in decimal.

• Output: 5
• System.out.println(20 >>> 2);
• Unsigned right shift the binary representation of 20 by 2 positions using the >>> operator.
• After unsigned right shifting by 2, 20 becomes 5 in decimal.

• Output: 5
• System.out.println(-20 >> 2);
• Right shift the binary representation of -20 by 2 positions using the >> operator.
• For negative numbers, the vacant leftmost positions are filled with the sign bit (1), and -20 becomes -5 in
decimal.
• Output: -5
• System.out.println(-20 >>> 2);
• Unsigned right shift the binary representation of -20 by 2 positions using the >>> operator.
• The unsigned right shift fills the vacant leftmost positions with 0, and -20 becomes a positive integer
(1073741819 in decimal).
• Output: 1073741819
Output:

TASK 9: Java AND Operator Example: Logical && and Bitwise &
public class OperatorExample9{

public static void main(String args[]){
int a=10;
int b=5;
int c=20;

System.out.println(a<b&&a<c);//false && true = false
System.out.println(a<b&a<c);//false & true = false
