Wap to generate multiplication table in java

import java.util.*; class multiplicationtable {     public static void main(String args[])     {         int i,n;//local variable         Scanner sc=new Scanner(System.in);         System.out.println("Enter the number");         n=sc.nextInt();         for(i=1;i<=10;i++)         {             System.out.println(n+"*"+i+"="+n*i);         }     } }

WAP in java to decide whether the two number is twin prime or not

import java.util.*; class loop11{ public static void main(String args[]) { int c1=0,c2=0,n1,n2,i,d; Scanner ob=new Scanner(System.in); System.out.println("enter two nos:"); n1=ob.nextInt(); n2=ob.nextInt(); for(i=1;i<=n1;i++) { if(n1%i==0) { c1++; } } for(i=1;i<=n2;i++) { if(n2%i==0) { c2++; } } d=Math.abs(n1-n2); if(c1==2 && c2==2 && d==2) System.out.println("twin prime"); else  System.out.println("not twin prime"); } }
