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:

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);
    }
}

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.
