与java数组有关的源代码如何转换为对应字节码

6. 4: return

7.

8. public static void main(ng.String[]);

9. Code:

10. 0: iconst_3

11. 1: newarray int

12. 3: astore_1 13. 4: return

14. }

例子2：

[java] view plaincopy

1. public class TestArray {

2. public static void main(String[] args){

3. int [] arr1={1,2,3};

4. }

5. }

生成的字节码文件如下：

[java] 1. public class TestArray extends ng.Object{

2. public TestArray();

3. Code:

4. 0: aload_0

5. 1: invokespecial #8; //Method java/lang/Object."<init>":()V

6. 4: return

7.

8. public static void main(ng.String[]);

9. Code:

10. 0: iconst_3

11. 1: newarray int

12. 3: dup

13. 4: iconst_0

14. 5: iconst_1

15. 6: iastore //将int value 和索引index 弹出栈，赋值arr[index]=value;

16. 7: dup

17. 8: iconst_1

18. 9: iconst_2

19. 10: iastore

20. 11: dup

21. 12: iconst_2
