java对象的赋值 java对象赋值不赋值地址

对象赋值都是按着地址赋值。。。具有相同的hash code

package experiment;

public class object{
	public String a ;
	object(){
		
	}
}

package experiment;

public class experiment1 {
	public static void main(String[] Zing) {
		object a = new object();
		object b = new object();
		object c = a;
		b = a;
		a.a = "nima";
		b.a = "caonima";
		System.out.println(a);
		System.out.println(b);
		System.out.println(c);
		System.out.println(a.a);
		System.out.println(b.a);
		System.out.println(c.a);
	}
