A: message one
B: message two
C: message three
D: message four
举一反三
- 以下程序段的输出结果为 【14】 。int x=0,y=4,z=5;if(x＞2)if(y＜5)System. out. println("Message one");elseSystem. out . println("Message two");else if(z＞5)System. out. println("Message three");elseSystem. out. println("Message four");
- 下列程序的运行结果? public class Test { public static void main(String a[]) { int x=3,y=4,z=5; if (x>3) { if (y<2) System.out.println("show one"); else System.out.println("show two"); } else { if (z>4) System.out.println("show three"); else System.out.println("show four"); } } }
- 下列程序段运行后的结果是（）int x = 1;int y = 2;x += y + y;if (x < 5 && y <= 4) {System.out.println("1");} else if (x >= 5 || y > 4) {System.out.println("2");} else {System.out.println("error");} A: 无法编译 B: 程序报错 C: 1 D: 2
- 以下程序段的输出结果是_________。 int x = 5, y = 6, z = 4; if (x + y > z && x + z > y && z + y > x) System.out.println("三角形"); else System.out.println("不是三角形");
- 下列程序的运行结果是______。 public class Test { public static void main (String[] args) { int x=3, y=4, z=5; if (x＞3) { if (y＜2) System.out.print ("show one"); else System.out.print ("show two"); } else{ if (z＞4) System.out.print ("show three"); else System.out.print ("show four"); } } } A: show one B: show two C: show three D: show four

设x=2以及y=3，下面代码的输出结果是。if (x >; 2)if（y >; 2）{int z = x + y;System.out.println("z is " + z) ;}else{System.out.println("x is " + x) ;} A: x is 2 B: z is 5 C: x is 5 D: 无输出
