您可能想要声明字段,并在构造函数中获取参数的值,并将参数保存到字段中:
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);
}
}
然后你可以像这样创建你的类的一个实例:
TCP_Ping ping = new TCP_Ping(5, "www.google.com");
