定义泛型类

好像c/c++里面也有这个东西，不过用的不多。

public class OverClass {

    private T over;
    public T getOver() {
        return over;
    }
    
    public void setOver(T over) {
        this.over = over;
    }
    
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        OverClassover1 = new OverClass();
        OverClassover2 = new OverClass();
        over1.setOver(true);
        over2.setOver(12.3f);
        boolean b = over1.getOver();
        float f = over2.getOver();
        System.out.println(b);
        System.out.println(f);
    }

}
