java中的逻辑运算符

public class Logic {
	public static void main(String[] args) {
	     boolean a = true;
	     boolean b = false;
	     System.out.println("a && b = " + (a&&b));
	     System.out.println("a || b = " + (a||b) );
	     System.out.println("!(a && b) = " + !(a && b));
	  }

}

编译并运行，结果如下

a && b = false
a || b = true
!(a && b) = true
