亲测三种办法解决：List用Remove方法报错

原创不易，转载请注明出处！

一、倒序删除

package com.cherrycheng.test;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class TestUseCase {
	public static void main(String[] args) {
		List<Integer> ids=new ArrayList<Integer>();
		Collections.addAll(ids, 1,2,3,4,5,6);
		
		for(int i=ids.size()-1;i>=0;i--){
			System.out.println(ids.get(i));
			ids.remove(new Integer(ids.get(i)));
		}
		
	}

}

二、用迭代器删除

package com.cherrycheng.test;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;

public class TestUseCase {
	public static void main(String[] args) {
		List<Integer> ids=new ArrayList<Integer>();
		Collections.addAll(ids, 1,2,3,4,5,6);
		
		for (Iterator<Integer> iter = ids.iterator(); iter.hasNext();)  
		{  
		    int item = iter.next();  
		    System.out.println(item);
		    //用迭代器删除
		    iter.remove();
		} 
		
	}

}

三、先根据中间值判断，再执行i++ 

package com.cherrycheng.test;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class TestUseCase {
	public static void main(String[] args) {
		List<Integer> ids=new ArrayList<Integer>();
		Collections.addAll(ids, 1,2,3,4,5,6,7);
		
		//先根据中间值判断，再执行i++  
		for(int i=0;i<ids.size();i++){  
			System.out.println(ids.get(i));
            if(ids.size()/2==i){  
            	ids.remove(i);  
                i--;  
            }  
        }  
		
	}

}
