Use a method in another method?
This is my code ( in BlueJ environment)
import java.io.*;
publicclass PrimePerfectSpecialMenu
{
privateint cu, nu, f;
private String n,c;
publicvoid check()throws IOException
{
InputStreamReader isr =new InputStreamReader(System.in);
BufferedReader br =new BufferedReader(isr);
System.out.println("Enter a number");
n=br.readLine();
System.out.println("1.Prime \n2.Perfect \n3.Special \n4.Quit");
c=br.readLine();
cu = Integer.parseInt(c);
int nu = Integer.parseInt(n);
switch(cu)
{
case 1:int a=0;
for(int i=1;i<=nu;i++)
{
if(nu%i==0)
a++;
}
if (a>2)
System.out.println("Not a prime number");
else
System.out.println("Prime number");
break;
case 2:int b=0;
for(int i=1;i<nu;i++)
{
if(nu%i==0)
b=b+i;
}
if (nu==b)
System.out.println("Perfect number");
else
System.out.println("Imperfect number");
break;
case 3:
}
}
privateint factorial(int a)
{
f=a;
a=a-1;
while(a!=0)
{
f=f*a;
a--;
}
return f;
}
}
I want to use the factorial method inside the case 3 of the switch statement, how would i go about doing this
I tried factorial fact = new factorial(), but it doesnt work( error : cannot resolve symbol class factorial)>
