设有类定义如下:
A: System.out.println(iArgs);
B: System.out.println(s);
C: System.out.println(iOther);
D: System.out.println(iam);
A: System.out.println(iArgs);
B: System.out.println(s);
C: System.out.println(iOther);
D: System.out.println(iam);
举一反三
- 请看下面的程序代码,当 n 为( )值时,程序段将输出字符串 second。 [br][/br] switch(n) { [br][/br] case 0: System .out .println(“first”); [br][/br] case 1: [br][/br] case 2: System .out .println(“second”); break; [br][/br] default: System .out .println(“end”); [br][/br] }(2.0) A: 0 B: 1 C: 2 D: 以上都可以
- 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”) ; } }
- 以下哪个是Java ArrayList 类的方法? A: add B: println C: import D: System
- System类中的println()方法分行显示信息,而print()方法不分行显示信息
- 【单选题】对于下面代码,正确的Java源程序文件名是( )。 class A { void method1() { System. out .println( "Method1 in class A" ); } } public class B { void method2() { System. out .println( "Method2 in class B" ); } public sta
