Compares two expressions and returns true only if both evaluate to true. Returns false if one or both evaluate to false. The following list shows all possible combinations:

true && false // Evaluates false because the second is false false && true // Evaluates false because the first is false true && true // Evaluates true because both are true false && false // Evaluates false because both are false

Examples

```
size(400, 400);
for (int i = 20; i <= 380; i += 20) {
  if ((i > 140) && (i < 240)) {
    stroke(0);  // Set color to black
  } else {
    stroke(255);  // Set color to white
  }
  line(120, i, 320, i);
}
