How do shift operators work in Java? [duplicate]

by 
System.out.println(Integer.toBinaryString(2 << 11));

Shifts binary 2(10) by 11 times to the left. Hence: 1000000000000

System.out.println(Integer.toBinaryString(2 << 22));

Shifts binary 2(10) by 22 times to the left. Hence : 100000000000000000000000

System.out.println(Integer.toBinaryString(2 << 33));

Now, int is of 4 bytes,hence 32 bits. So when you do shift by 33, it’s equivalent to shift by 1. Hence : 100
