Weird result of Java Integer left shift

Question

I\'m a little confused now by java left shift operation,

1<<31 =  0x80000000  --> this I can understand

But

1<         


        

Answer 1

System.out.println(Integer.toBinaryString(1 << 32)); 

Shifts binary 1(10) by 32 times to the left. Hence: 1 in decimal

System.out.println(Integer.toBinaryString(1 << 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 : 2 in decimal
