int a = 2; System.out.println(a++); System.out.println(a); System.out.println(++a); 程序的输出结果是 ( )
A: 2 3 4
A: 2 3 4
举一反三
- int a = 2; System.out.println(a++); System.out.println(a); System.out.println(++a); 程序的输出结果是 ( ) A: 2 3 4
- 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");
- 中国大学MOOC: 下列代码中构造方法的返回类型是（）public class Village { Village () { System .out .println(“hiding in Village”) ; } public static void main( String args [ ]) { Village c =new Village ( ) ;}class Village { public static void main( String args [ ]) { Village c =new Village ( ) ; } Village () { System .out .println(“hiding in Village”) ; } }
- 以下代码段的输出结果为1. int x = 0, y = 4, z = 5;2. if (x > 2) {3. if (y < 5) {4. System. out .println ( "message one" );5. }6. else {7. System.out.println( "message two");8. }9. }10. else if (z > 5) {11. System.out.println("message three");12. }13. else {14. System.out.println( "message four");15. } A: message one B: message two C: message three D: message four
- 下列程序段的输出结果为______。 int a=2; switch(a) case 2: System.out.println("Value is 2."); case 3: System.out.println("Value is 3."); break; default: System.out.println("end"); break;
