Java 中的 clone( ) 和 new哪个效率更高

package com.miivii.javalib;

public class Bean implements Cloneable {
    private String name;

    public Bean(String name) {
        this.name = name;
    }

    @Override
    protected Bean clone() throws CloneNotSupportedException {
        return (Bean) super.clone();
    }
}
package com.miivii.javalib;

public class TestClass {
    private static final int COUNT = 10000 * 1000;

    public static void main(String[] args) throws CloneNotSupportedException {

        long s1 = System.currentTimeMillis();

        for (int i = 0; i < COUNT; i++) {
            Bean bean = new Bean("ylWang");
        }

        long s2 = System.currentTimeMillis();

        Bean bean = new Bean("ylWang");
        for (int i = 0; i < COUNT; i++) {
            Bean b = bean.clone();
        }

        long s3 = System.currentTimeMillis();

        System.out.println("new  = " + (s2 - s1));
        System.out.println("clone = " + (s3 - s2));
    }
}

package com.miivii.javalib;

public class Bean implements Cloneable {
    private String name;
    private String firstSign;//获取名字首字母

    public Bean(String name) {
        this.name = name;
        if (name.length() != 0) {
            firstSign = name.substring(0, 1);
            firstSign += "abc";
        }
    }

    @Override
    protected Bean clone() throws CloneNotSupportedException {
        return (Bean) super.clone();
    }
}
