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。

下面的代码中有什么错误吗？_______
using System;
class A
{
public virtual void F(){
Console.WriteLine("A.F");
}
}
abstract class B:A
{
public abstract override void F();
}
interface A{
int x = 0;
}
class B{
int x =1;
}
class C extends B implements A {
public void pX(){
System.out.println(x);
}
public static void main(String[] args) {
new C().pX();
}
}
class Something {
int i;
public void doSomething() {
System.out.println("i = " + i);
}
}
有什么错呢？ 看不出来啊。
判断：
public class test
{
private static String s="string";
public static void main(String a[])
{
String t="strin"+"g";
System.out.println(s==t);
}
}
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。
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。
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？
A.public class MyClass{}
B.class MyClass{}
C.abstract class MyClass{}
D.final class MyClass{}
