What does shuffle mean in java?

The shuffle function in Java can be implemented through the Collections.shuffle(List list) method, which scrambles the order of elements in the specified list so that it has an unpredictable order. Usage: Import the Collections class, call the shuffle method, and pass the collection to be shuffled as a parameter.

shuffle in Java

In Java, shuffle is a shuffled collection The process of element ordering. This is typically used to create random lists or perform random selections.

The shuffle

function in Java can be implemented through the

Collections.shuffle(List list) method accomplish. This method rearranges the elements in the specified list in random order, giving them an unpredictable order. Usage

To shuffle a Java collection, you can perform the following steps:

Import

java.util.Collections

kind.
1. Call the shuffle
method and pass the collection to be shuffled as a parameter.
2. For example:

<code class="java">import java.util.Collections;
import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        // 创建一个字符串列表
        ArrayList<String> list = new ArrayList<>();
        list.add("Java");
        list.add("Python");
        list.add("C++");

        // 打乱列表中的元素
        Collections.shuffle(list);

        // 打印打乱后的列表
        System.out.println(list);
    }
}</code>

The result may look like:

<code>[C++, Python, Java]</code>

Note

##shuffle

Method will change the order of the original collection.

• Random number generation in Java is pseudo-random, which means it is generated by an algorithm rather than a true source of randomness. You can also use other libraries or custom algorithms to implement the shuffle function.
