取反顶折取反!真变为假假变为真public class HelloWorld { public static void main(String[] args) { boolean b = true; System.out.println(b); //输出true System.out.println(!b);//输出false }}异或^顶折异或^不同，返回真相同，返回假public class HelloWorld { public static void main(String[] args) { boolean a = true; boolean b = false; System.out.println(a^b); //不同返回真 System.out.println(a^!b); //相同返回假 }}逻辑运算符int i = 1;boolean b = !(i++ == 3) ^ (i++ ==2) && (i++==3);System.out.println(b);System.out.println(i);
