Question

stringstream中的东西怎么遍历

Answer 1

import java.util.ArrayList;
import java.util.Iterator;

public class Test {
public static void main(String[] args) {
ArrayList list = new ArrayList();
list.add(5);
list.add(8);
list.add(9);
//案 推荐 .简洁
for (Integer e : list) {
System.out.print(e + ",");
}
//案二
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
//案三
Iterator it = list.iterator();
while (it.hasNext()) {
System.out.println(it.next());
}

}
}
