下列程序的运行结果是【 】。public class Test {public static void main (String args[]) {String s1="hello!";System.out.println (s1.toUpperCase());}}

下面程序创建了一个线程并运行,请填空,使程序完整。public class ThreadTest {public static void main (String[] args) {Hello h=Hew Hello ();【 】t.start ();}}class Hello implements Runnable {int i;public void run () {while(true) {System.out.println("Hello" +i++);if(i==5) break;}}}

通过实现Rmmable接口创建线程,请在下面横线处填写代码完成此程序。public class ThreadTest{public static void main(String args []){Thread testObj1 = new Thread (new Hello ());Thread testObj2 = new Thread (new Hello ());testObj 2.start ( );}}class Hello implements Runnable{int j;public void run(){System.out.println("Hello" + j ++);}}

请在下划线处填入代码,是程序正常运行并且输出 “ Hello! ”Class Test 【 15 】 {Public static void main (String[] arge){Test t = new Test();t.start();}Public void run(){System.out.println( “ Hello! ” );}
