int a = 205;   // In binary: 11001101
int b = 45;    // In binary: 00101101
int c = a | b; // In binary: 11101101
println(c);    // Prints "237", the decimal equivalent to 11101101


int a = 255 << 24; // Binary: 11111111000000000000000000000000

Compares each corresponding bit in the binary representation of the values. For each comparison two 1's yeild 1, 1 and 0 yeild 1, and two 0's yeild 0. This is easy to see when we look at the binary representation of numbers

  11010110  // 214
& 01011100  // 92
  --------
  11011110  // 222

To see the binary representation of a number, use the binary() function with println(). value | value2 value1 int, char, byte value2 int, char, byte & (bitwise AND) binary() 1.0 Operator PDE Extended
