智慧职教: 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; }

public class Example {     public static void main(String[] args) {         new Father () {             public void show() {                 System.out.println("helloworld");             }         }.show();     } } class Father {     public void show() {         System.out.println("hellofather");     } }

从下面四段代码中选择出正确的代码段（） A: 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;} B: public class Something {void doSomething () {private String s = ̶”;int l = s.length();}} C: abstract class Name {private String name;public abstract boolean isStupidName(String name) {}} D: public class Something {public int addOne(final int x) {return ++x; }}
