m,n均为正整数
public class IsPrime {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int m = sc.nextInt();
int n =sc.nextInt();
}
private static void isPrime(int m,int n){
int j,k;
int amount = 0;//素数的个数(已知m<n)
j = m;
k = n;
for (int i = j; i <= n; i++) {
int temp = 0;
for (int t = 1; t <= i; t++) {
if(i%t==0){
temp++;
}
}
if(temp<=2){
amount++;
}
}
System.out.println("素数总数是"+amount);
}
}
