例如:int a = 10;
int b = 10;
System.out.println(a==b);
输出都是true
------------------------------------------------
如果是对象比较 Integer c = new Integer(10);
Integer d = new Integer(10);
System.out.println(c==d);
那么输出是false
------------------------------------------------
如果是基本类型和对象(仅限于基本类类型的对象,Integer,Float,等等)
float f1 = 4.2f;
Float f2 = new Float(4.2f);
System.out.println(f1==f2);
那么输出是true
