stream has already been operated upon or closed错误

在学习JDK1.8新特性时Stream流的过程中遇到了一个错误

import java.util.stream.Stream;public class Demo05Stream_filter {public static void main(String[] args) {//获取一个Stream流Stream<String> stream = Stream.of("张三", "李四", "王五", "赵六", "田七");//调用filter方法//过滤之后有3个元素Stream<String> stream1 = stream.filter((String name)->{return name.startsWith("张");});stream.forEach(name->System.out.println(name));}
}

运行系统报错

错误提示，stream流已经被关闭了
仔细查找原来是这一句出现了问题

stream.forEach(name->System.out.println(name));

他stream已经执行过被关闭了
把他改为

stream1.forEach(name->System.out.println(name));

即可
