怎么样才能用jAvA写出生成4%6的随机整数

Random rand = new Random();for(int i=1;i

用概率模型,先随机一次看取用哪个概率,随后再随机一次。代码示例如下: import java.util.Random;public class HelloWorld { public static void main(String[] args) { Random random = new Random(); double p1=0.7; //1~4的概率 double p=(...

Java语言可以通过Random类的对象来实现1-6随机数的生成方法,代码如下: import java.util.Random;public class Radom{ public static void main(String[] strs){ Random rand = new Random(); System.out.println(rand.nextInt(5)+1); }}

Option Base 1 Private Sub Form_Click() Dim a(36) As Integer, b(6, 6) As Integer, i As Integer, j As Integer, num As Integer Print "原矩阵:" Randomize For i = 1 To 36 a(i) = Int((99 - 10 + 1) * Rnd + 10) Print a(i); num = num +...

package keshe4; import java.util.Scanner; public class CountSum { public static void main(String[] args) { // TODO Auto-generated method stub Scanner sc = new Scanner(System.in); int num = sc.nextInt(); String numStr = num + ""...

public class Test1 { public static void main(String[] args) { int sum=0; for(int i=2;i

=CHOOSE(LOOKUP(RAND(),{0;0.1;0.3;0.5;0.6;0.75},{1;2;3;4;5;6}),11,12,13,14,15,16) 但是概率不同于比例,存在这种概率不代表一定会出现。

可以首先遍历数组,所有位都填上1, 然后生成5个在0-19间的随机数,然后依次填入2,3,4,5,6, 如果生成的随机位上已经不是1,则再取下一个随机数。 随机数用java.util.random类: import java.util.Random;Random random = new Random();int s = ...

import java.util.Scanner;public class Test456 {public static void main(String[] args) {Scanner sc = new Scanner(System.in);System.out.println("输入一个小数:");double x = sc.nextDouble();int y = f456(x);System.out.println(y);}p...

6&5 =4; 4*3
