Java程序生成自定义随机数-1或1
要生成自定义随机数1或-1，您需要使用nextBoolean()。首先，循环并在每次迭代中创建一个Random对象-
for (int i = 0; i < 5; i++) {
Random rand = new Random();
}现在，用于nextBoolean()在TRUE条件下生成ekse-1-
for (int i = 0; i < 5; i++) {
Random rand = new Random();
if (rand.nextBoolean())
System.out.println(1);
else
System.out.println(-1);
}示例
import java.util.Random;
public class Demo {
public static void main(String[] args) {
for (int i = 0; i < 5; i++) {
Random rand = new Random();
if (rand.nextBoolean())
System.out.println(1);
else
System.out.println(-1);
}
}
}输出结果
1 -1 -1 -1 -1
