从Java LinkedHashMap删除值
使用该remove()方法从LinkedHashMap中删除单个值-
首先，创建一个LinkedHashMap并添加一些元素-
LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();
l.put("1", "Jack");
l.put("2", "Tom");
l.put("3", "Jimmy");
l.put("4", "Morgan");
l.put("5", "Tim");
l.put("6", "Brad");现在，假设您需要从LinkedHashMap中删除元素2。为此，请使用remove()方法-
Object ob = l.remove("2");以下是从Java中的LinkedHashMap中删除值的示例-
示例
import java.util.*;
public class Demo {
public static void main(String[] args) {
LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();
l.put("1", "Jack");
l.put("2", "Tom");
l.put("3", "Jimmy");
l.put("4", "Morgan");
l.put("5", "Tim");
l.put("6", "Brad");
System.out.println("LinkedHashMap elements...\n"+l);
//删除一个元素
Object ob = l.remove("2");
System.out.println("\nLinkedHashMap elements after removing an element...\n"+l);
}
}输出结果
LinkedHashMap elements...
{1=Jack, 2=Tom, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad}
LinkedHashMap elements after removing an element...
{1=Jack, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad}
