我正在使用Java 7中的转义分析进行一些测试,以便更好地了解哪些对象有资格进行堆栈分配.

这是我编写的用于测试堆栈分配的代码:

import java.util.ArrayList;
import java.util.Iterator;


public class EscapeAnalysis {

    private static final long TIME_TO_TEST = 10L * 1000L; // 10s

    static class Timestamp {
        private long millis;
        public Timestamp(long millis) {
            this.millis = millis;
        }
        public long getTime() {
            return millis;
        }
        public void setTime(long time) {
            millis = time;
        }
    }

    public static void main(String[] args) {
        long r = 0;
        System.out.println("test1");
        r += test1();
        System.out.println("test2");
        r += test2();
        System.out.println("test3");
        r += test3();
        System.out.println("test4");
        r …
