看一块这样的代码

    1. public class UserJvmTest {
    2. public static final Integer age = 20;
    3. Integer id;
    4. String name;
    5. public int cal() {
    6. int a = 1;
    7. int b = 2;
    8. int c = (a + b) * 10;
    9. return c;
    10. }
    11. public static void main(String[] args) {
    12. UserJvmTest userJvmTest = new UserJvmTest();
    13. userJvmTest.cal();
    14. }
    15. }

    反汇编后的结果:
