你可能想声明领域,并获得在构造函数中的参数值,参数保存到字段:
public static class TCP_Ping implements Runnable {
// these are the fields:
private final int a;
private final String b;
// this is the constructor, that takes parameters
public TCP_Ping(final int a, final String b) {
// here you save the parameters to the fields
this.a = a;
this.b = b;
}
// and here (or in any other method you create) you can use the fields:
@Override public void run() {
System.out.println("a: " + a);
System.out.println("b: " + b);
}
}
然后你就可以像这样创建类的实例:
TCP_Ping ping = new TCP_Ping(5, "www.google.com");
我建议你[Java中开始](http://docs.oracle.com/javase/tutorial/java/javaOO/index.html)。 关于您的问题:http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html – blint 2013-04-06 01:48:03
类不是“静态”。方法,实例变量和初始化块可以是'static'。然而,人们滥用这一点。 – 2013-04-06 02:30:40
