Java 实例 - List 截取
以下实例演示了如何使用 Collections 类的 indexOfSubList() 和 lastIndexOfSubList() 方法来查看子列表是否在列表中,并查看子列表在列表中所在的位置: Main.java 文件 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 ) ;
List sublist = Arrays . asList ( " three Four " . split ( " " ) ) ;
System . out . println ( " 子列表 : " + sublist ) ;
System . out . println ( " indexOfSubList: "
+ Collections . indexOfSubList ( list , sublist ) ) ;
System . out . println ( " lastIndexOfSubList: "
+ Collections . lastIndexOfSubList ( list , sublist ) ) ;
}
} |
以上代码运行输出结果为:
List :[one, Two, three, Four, five, six, one, three, Four]
子列表 :
indexOfSubList: 2
lastIndexOfSubList: 7
