从Java中的数组中删除负数
以下程序显示了如何从数组中删除负数。
示例
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class Tester {
public static void main(String[] args) {
List<Integer> objArray = new ArrayList<Integer>();
objArray.clear();
objArray.add(2);
objArray.add(-3);
objArray.add(4);
System.out.println("Array before removing an element "+objArray);
Iterator<Integer> iterator = objArray.iterator();
while(iterator.hasNext()) {
Integer next = iterator.next();
if(next < 0) {
iterator.remove();
}
}
System.out.println("Array after removing an element"+objArray);
}
}输出结果
Array before removing an element [ 2, -3, 4 ] Array after removing an element [ 2, 4 ]
