Java—正整数分解成质因数

public static void main(String[]args){Scanner sc=new Scanner(System.in);int n=sc.nextInt();Decompose(n);}//用于分解private static void Decompose(int n){System.out.print(n+"=");for(int i=2;i<=n;i++){while(n%i==0 && n!=i){n=n/i;System.out.print(i+"*");}if(n==i){System.out.println(i);break;}}}
