int x = 50;
x += (x << 2) + 1;

Noncompliant Code Example (Left Shift)

This noncompliant code example segrates arithmetic and bitwise operators by variables. The x variable participates only in bitwise operations, and y participates only in arithmetic operations.

int x = 50;
int y = x << 2;
x += y + 1;

This example is noncompliant because the actual data receives both bitwise and arithmetic operations performed on it, even though they are segregated into different variables.

Compliant Solution (Left Shift)

...

byte[] b = new byte[] {-1, -1, -1, -1};
int result = 0;
for (int i = 0; i < 4; i++) {

  result = ((result << 8) | (b[i] & 0xff));
}
