java代码----equals和==区别

总结：

==的意义在于比较的是整型

package com.aa;

//
public class Bd {
	public static void main(String[] args) {
		Integer i1 = 124;
		Integer i2 = 124;
		Integer i3 = 125;
		Integer i4 = 125;
		System.out.println(i1 == i2);
		System.out.println(i1.equals(i2));
		System.out.println(i3 == i4);
	}
}
