Integer i1 = new Integer(127);
Integer i2 = new Integer(127);
System.out.println(i1 == i2);
System.out.println(i1.equals(i2));
Integer i3 = new Integer(128);
Integer i4 = new Integer(128);
System.out.println(i3 == i4); System.out.println(i3.equals(i4));
Integer i5 = 127;
Integer i6 = 127;
System.out.println(i5 == i6);
System.out.println(i5.equals(i6));
Integer i7 = 128;
Integer i8 = 128;
System.out.println(i7 == i8);
System.out.println(i7.equals(i8));
结果是false true----false true-----true true----false true i5 i6 i7 i8的结果为什么是这样
