此处,Something 类的文件名叫OtherThing.java

class Something {

private static void main(String[] something_to_do) {

System.out.println("Do something ...");

}

}

这个好像很明显。

下列选项中的 方法可以正确地加入类Child中,且父类的方法不会被覆盖。 public class Parent{ public int addValue(int a,int b){ int s; s=a+b; return s; } } class Child extends Parent{ }A.int addValue(int a,int b){∥do something…}B.public void addValue( ){∥do something…}C.public int addValue(int a,int b)throws MyException{∥do something…}D.public float addValue(int a,int b,float b=1.0){∥do something…}

有如下程序段: public class Parent { public int addValue (int a,intB){ int s; s=a+b; return 3; } } class Child extends Parent {} 则下列选项中,可以正确加入类Child中且父类的方法不会被覆盖的是( )。A.int addValue (int a,intB){//do something...}B.public void addValue() {//do something...}C.public int addValue (int a,intB)throws MyException {//do something...}D.public float addValue (int a,int b,float b=1.0) {//do someting...}

下列程序的输出结果是_______。class Test{public static void main(String args []){int m=6;do{m--:}while(m>0);System.out.println("m="+m);}}

阅读下列代码段,选出该代码段的正确的文件名( )。 class A { void method () { System.out.println ("methodl in class A"); } } public class B { void method2 () { System.out.println("method2 in class B"); } public static void main (String args[]) { System.out.println ("main () in class B"); } }A.A.javaB.A.classC.B.classD.B.java

public class Something {void doSomething () {private String s = "";int l = s.length();}}有错吗?

abstract class Something {private abstract String doSomething ();}这好像没什么错吧?

public class Something {public static void main(String[] args) {Other o = new Other();new Something().addOne(o);}public void addOne(final Other o) {o.i++;}}class Other {public int i;}和上面的很相似,都是关于final 的问题,这有错吗?

public class Something {public static void main(String[] args) {Something s = new Something();System.out.println("s.doSomething() returns " + doSomething());}public String doSomething() {return "Do something ...";}}看上去很完美。
