如何在java中读入整数

import java.util.Scanner

public class Demo {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in)

System.out.println("请输入一个明巧谈宽拦整数")

int x = scan.nextInt()

System.out.println("输入的证激碰书是："+x)

}

下面是我刚写的代渣睁码，实现的方法对你有帮助

public class Test1 {

public static void main(String[] args) {

int[] counts = new int[20]

for(int i = 0i <20i++){

counts[i] = (int)(Math.random() * 10)//随稿银机0到9之间的整数

System.out.print(counts[i] + " ")

}

System.out.println()

int [] number = check(counts)

int [] newnumber = new int[10]

int length = 9

for(int k = 0k <10k++){

newnumber[k] = number[length]

length--

}

String output = ""

for(int j = 0 j <10j++){

if(newnumber[j] != 0)

output += j + " appear " + newnumber[j] + ((newnumber[j] == 1) ? " time\n" : " times\n")

}

System.out.println(output)

}

//统键梁宴计每个数出现的次数

public static int[] check(int[] counts){

int[] number = new int[10]

for(int i = 0i <20i++)

number[9 - counts[i]]++

return number

}

}
