分析以下运算程序的运行结果,并上机运行验证。 public static void main(String[] args) { int a = 15; int b = 2; int x = a & b; int y = a | b; int z = a ^ b; boolean b1, b2, b3 = true, b4 = true; b1 = a < b & (b3 = x > y); b2 = a < b && (b4 = x > y); System.out.println(a + "&" + b + "=" + x); System.out.println(a + "|" + b + "=" + y); System.out.println(a + "^" + b + "=" + z); System.out.println("b1=" + b1); System.out.println("b2=" + b2); System.out.println("b3=" + b3); System.out.println("b4=" + b4); }
