Since an int is a 32-bit variable, shifting by more than (-)31 is confusing at best and an error at worst. Shifting an int by 32 is the same as shifting it by 0, and shifting it by 33 is the same as shifting it by 1.

Similarly, shifting a long by (-)64 is the same as shifting it by 0, and shifting it by 65 is the same as shifting it by 1.

Noncompliant Code Example

public int shift(int a) {
  return a << 48;
}

Compliant Solution

public int shift(int a) {
  return a << 16;
}
