Kotlin基本类型自动装箱出现问题解决办法

val a: Int = 10000
print(a === a) // Prints 'true'
val boxedA: Int? = a
val anotherBoxedA: Int? = a
print(boxedA === anotherBoxedA) // !!!Prints 'false'!!!

fun main(args: Array<String>) {
 test1()
}

fun test1() {
 val i: Int = 1000
 println(i)
}

public static final void test1() {
  short i = 1000;
  System.out.println(i);
 }

fun main(args: Array<String>) {
 test2()
}

fun test2() {
 val i: Int? = 1000
 println(i)
}

val i: Int? = 1000

 public static final void test2() {
  Integer i = Integer.valueOf(1000);
  System.out.println(i);
 }

fun test3() {
 //Kotlin并不会自动装箱
 val i: Int = 1000

 println(i)

 //因为j和k都被当做对象操作，因此会将i进行装箱做操，然后复制给j、k
 val j: Int? = i
 val k: Int? = i

 println(j === k)
}

public static final void test3() {
  short i = 1000;
  System.out.println(i);
  Integer j = Integer.valueOf(i);
  Integer k = Integer.valueOf(i);
  boolean var3 = j == k;
  System.out.println(var3);
}
