public static void main(String[] args) {
        answer(10,60);

    }
    public static void answer(int m,int k){
        AtomicInteger n = new AtomicInteger(m);
        Stream<Integer> stream = Stream.generate(() -> n.incrementAndGet()).limit(k);
        System.out.println(Arrays.toString(stream.toArray()));
    }

System.out.println(列表);对我有用。

下面是一个完整的例子:

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

public class HelloWorld {
     public static void main(String[] args) {
        final List<String> list = new ArrayList<>();
        list.add("Hello");
        list.add("World");
        System.out.println(list);
     }
}

它将打印[Hello, World]。

或者你可以简单地使用Apache Commons实用程序:

https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/ArrayUtils.html#toString-java.lang.Object-

List<MyObject> myObjects = ...
System.out.println(ArrayUtils.toString(myObjects));

下面是一些关于打印list组件的例子:

public class ListExample {

    public static void main(String[] args) {
        List<Model> models = new ArrayList<>();

        // TODO: First create your model and add to models ArrayList, to prevent NullPointerException for trying this example

        // Print the name from the list....
        for(Model model : models) {
            System.out.println(model.getName());
        }

        // Or like this...
        for(int i = 0; i < models.size(); i++) {
            System.out.println(models.get(i).getName());
        }
    }
}

class Model {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

从Java 8开始，List继承了一个默认的“forEach”方法，你可以将它与方法引用“System”结合起来使用。输出::println”像这样:

list.forEach(System.out::println);

For循环输出列表的内容:

List<String> myList = new ArrayList<String>();
myList.add("AA");
myList.add("BB");

for ( String elem : myList ) {
  System.out.println("Element : "+elem);
}

结果:

Element : AA
Element : BB

如果你想打印在单行(只是为了信息):

String strList = String.join(", ", myList);
System.out.println("Elements : "+strList);

结果:

Elements : AA, BB
