下面代码的运行结果为:( )import java.io.*;import java.util.*;public class foo{public static void main (String[] args){String s;System.out.println(s= + s);}}
读代码:public class Test {public static void main (String args[]) {class Foo {public int i = 3;}Object o = (Object) new Foo();Foo foo = (Foo)o;System.out.println(foo.i);}}结果是:
读代码:public class ExceptionTest {class TestException extends Exception {}public void runTest () throws TestException {}public void test () /* Point X*/ {runTest ();}}第4行//point X 位置, 加哪行代码能让代码可编译
读代码:public class Test {public static void main (String [] args) {String foo = “blue”;String bar = foo;foo = “green”;System.out.println(bar);}}结果是:
读代码:1. public interface Foo{2.int k = 4;3. }Which three are equivalent to line 2? (Choose Three)
下面的程序段执行结果是 public class Foo { public static void main(String[] args) { try{ return; }finally { System.out.println("finally"); } } }
10、以下程序代码运行时输出的结果是()。public class Foo{ public static void main(String[] args){ try{ System.out.print('A'); foo1(); System.out.print('B'); }catch(RuntimeException e){ System.out.print('C'); }catch(Exception e){ System.out.println('D'); } } public static void foo1() throws RuntimeException{ throw new RuntimeException(); } }
