How to design a overloaded function. java icse class 10

Make class Check to design the overloaded function primes() as:
i. void primes(long num) – To print only prime digits from the number stored in ‘num’.
ii. void primes(int n,int m) – To print whether ‘n’ and ‘m’ are Twin-Prime or not otherwise print a suitable message. Two numbers are said as Twin-Prime if both the numbers are prime and their difference is 2.

import java.util.*;
class Check
{
public static void primes (long num)
{
long x=num,d=0,y=0,i=0;
while(x>0)
{
d=x%10;
y=d;
for(int j = 2 ; j<y ; j++)
{
if(y%j==0)
i++;
}
if(i==0)
System.out.println(d);
x=x/10;
i=0;
}
}
public static void primes( int n ,int m)
{
int x=n,y=m,d=0,j=0;
for(int i = 2 ; i<x ; i++)
{
if(x%i==0)
d++;
}
for(int t = 2 ; t<y ; t++)
{
if(y%t==0)
j++;
}
if(d==0 && j==0)
{
if(n>m)
{
int l = n-m;
if(l==2)
System.out.println(“These are Twin Prime numbers”);
else
System.out.println(“These are not Twin Prime numbers”);
}
else
{
int l = m-n;
if(l==2)
System.out.println(“These are Twin Prime numbers”);
else
System.out.println(“These are not Twin Prime numbers”);
}
}
else
System.out.println(“These are not Twin Prime numbers”);
}
public static void main()
{

Scanner in = new Scanner(System.in);
System.out.print(“Enter a number = “);
long num = in.nextLong();
primes(num);
System.out.print(“Enter two numbers = “);
int n = in.nextInt(),m = in.nextInt();
primes(n,m);
}
}

In this post i have shared a java program which is mostly asked by students of computer science.
