Object传入String类型和其他

是可以传入的。

package com.sun.test;

public class Test03 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Test03 t3 = new Test03();
        String s = "hello";
        String re = t3.Str(s);
        System.out.println(re);
        int i = 10;
        String re1 = t3.Nnm(i);
        System.out.println(re1);

    }

    public String Str(Object c){
        //System.out.println(c);
        return c.toString();
    }
    public String Nnm(Object c){
        //System.out.println(c);
        return c.toString();
    }

}
