删除阵列的jList特定元素上面的代码

Question

我想从阵列输出在JList中删除项目

String[] cdList = {"Adele", "Drake", "Prince", "Rihanna", "Sia"} ; 

输出

String[] cdList = {"Adele", "Drake", "Prince", "Sia"} ; 

Answer 1

这会帮助你：

List<String> list = new ArrayList<String>(Arrays.asList(cdList)); 
list.remove(cdList[i]); 
cdList = list.toArray(new String[0]); 

我已经写成这样，享受！

String[] cdList = {"Adele", "Drake", "Prince", "Rihanna", "Sia"} ; 

for(int i = 0; i< cdList.length;i++){ 
    System.out.println(i+1 + " . " + cdList[i]); 
} 
System.out.println("Enter the number of the name you want to remove:"); 
Scanner scan = new Scanner(System.in); 
int num = scan.nextInt(); 
List<String> list = new ArrayList<String>(Arrays.asList(cdList)); 
list.remove(cdList[num-1]); 
cdList = list.toArray(new String[0]); 
for(int i = 0; i< cdList.length;i++){ 
    System.out.println(i+1 + " . " + cdList[i]); 
} 

干杯！
