应该注意的是,返回值不同,其它都相同不算是重载。

- 方法重载 例子
|
||||
```java
|
||||
class DisplayOverloading
|
||||
{
|
||||
public void disp(char c)
|
||||
{
|

System.out.println(c);

public void disp(char c, int num)
|

{

System.out.println(c + " "+num);
|

}

class Sample
|

{
|

public static void main(String args[])
|

{
|

DisplayOverloading obj = new DisplayOverloading();
|

obj.disp('a');
|
||||
obj.disp('a',10);
|

}
|

|

DisplayOverloading obj2 = new DisplayOverloading('a',10);
|

# 七、反射
|
||||
|
||||
每个类都有一个 **Class** 对象,包含了与类有关的信息。当编译一个新类时,会产生一个同名的 .class 文件,该文件内容保存着 Class 对象。
