如果下列的方法能够正常运行，在控制台上将显示什么？（）publicvoidexample(){try{unsafe();System.out.println("Test1");}catch(SafeExceptione){System.out.println("Test2");}finally{System.out.println("Test3");}System.out.println("Test4");}
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”) ; } }
- 下面程序的执行结果是（ ）。public class Test {public static void main(String[] args) {new Test().test();}public void test(){try{System.out.print("try");}catch(ArrayIndexOutOfBoundsException e){System.out.print("catch1");}catch(Exception e){System.out.print("catch2");}finally{System.out.println("finally");}}} A: try finally B: try catch1 finally C: try catch2 finally D: finally
- System类中的println()方法分行显示信息，而print()方法不分行显示信息
- 对于下列Test.java代码， 下列哪个叙述是正确的? public class Test{ public static void main(String args[]){ int arr[] = new int[10]; System. out . println(arr[1]); } }
