&& (logical AND) Control Logical Operators Web & Application logicalAND.gif for(int i=5; i<=95; i+=5) { if((i > 35) && (i < 60)) { stroke(0); //Set color to black } else { stroke(255); //Set color to white } line(30, i, 80, i); } 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
