使用Java中的ListIterator从ArrayList中删除元素
可以使用ListIterator方法从ArrayList中删除元素remove()。此方法删除ArrayList中的当前元素。如果该remove()方法之前没有该next()方法，则抛出IllegalStateException异常。
演示该程序的程序如下。
示例
import java.util.ArrayList;
import java.util.ListIterator;
public class Demo {
public static void main(String[] args) {
ArrayList<String> aList = new ArrayList<String>();
aList.add("Apple");
aList.add("Mango");
aList.add("Guava");
aList.add("Orange");
aList.add("Peach");
System.out.println("The ArrayList elements are: ");
for (String s: aList) {
System.out.println(s);
}
ListIterator li = aList.listIterator();
li.next();
li.remove();
System.out.println("\nThe element Apple is removed");
System.out.println("\nThe ArrayList elements are: ");
for (String s: aList) {
System.out.println(s);
}
}
}输出结果
上面程序的输出如下-
The ArrayList elements are: Apple Mango Guava Orange Peach The element Apple is removed The ArrayList elements are: Mango Guava Orange Peach
