以下实例演示了如何使用 collections 类的 replaceall() 来替换list中所有的指定元素:

main.java
*/
import java.util.*;
public class main {
public static void main(string[] args) {
list list = arrays.aslist("one two three four five six one three four".split(" "));
system.out.println("list :"+list);
collections.replaceall(list, "one", "hundread");
system.out.println("replaceall: " + list);
}
}
以上代码运行输出结果为:
list :[one, two, three, four, five, six, one, three, four]
replaceall: [hundread, two, three, four, five, six, hundread, three, four]
以上就是java 实例 - list 元素替换的内容。
