Program:

            /* ............... START ............... */
                
public class JavaLeftShift {

	/* left shif Operators */

	public static void main(String args[]) {

		System.out.println(1 << 2);// 1*2^2=1*4=4
		System.out.println(1 << 3);// 1*2^3=1*8=8
		System.out.println(1 << 4);// 1*2^4=1*16=16
		System.out.println(11 << 2);// 11*2^2=11*4=44
		System.out.println(14 << 3);// 14*2^3=14*8=112

	}

}
                /* ............... END ............... */
        

Output

4
8
16
44
112

Notes:

• Left shift operator "<<" shifts a bit pattern to the left.
• For Eg : 10 << 2 - Here bit of 10 moves to left two place and fill the right place with zero.
• If the left side operand is one ( 1 << 2) we can use like 2^n.
• Due to left shift of values , we will get the result as high value than input. But for right shift we will get the smaller value than input.
