  nextBoolean()方法在java.util包中可用。

• nextBoolean() method is used to return the next pseudo-random Boolean value from this Random Value Generator.

  nextBoolean()方法用于从此“随机值生成器”返回下一个伪随机布尔值。

• nextBoolean() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  nextBoolean()方法是一个非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

Example:

例：

// Java program to demonstrate the example 
// of boolean nextBoolean() method of 
// Random
import java.util.*;
public class NextBooleanOfRandom {
public static void main(String args[]) {
// Instantiates Random object
Random ran = new Random();
// By using nextBoolean() method is
// to return the next to next
// pseudo-random boolean value from
// this Random Value Generator
boolean val = ran.nextBoolean();
// Display val
System.out.println("ran.nextBoolean(): " + val);
}
}
