I am new to this.Can u guys help me?


import java.util.Scanner;
class IngeniusXD
{Scanner scn = new Scanner(System.in);
 private static String Simplify(String cal ,char st ,char nd ,char rep)
 {for (int i = 0;i < cal.length() - 100; i++)
  {if ((cal.charAt(i) == st) || (cal.charAt(i + 1) == nd))
   {cal = cal.substring(0 ,i - 1) + rep + cal.substring(i + 2);}
   else if ((cal.charAt(i) == nd) || (cal.charAt(i + 1) == st))
   {cal = cal.substring(0 ,i - 1) + rep + cal.substring(i + 2);}}
  return cal;}
 public static String Simplify_General(String cal)
 {cal = Simplify(cal ,'+' ,'-' ,'-');
  cal = Simplify(cal ,'-' ,'-' ,'+');
  cal = Simplify(cal ,'+' ,'+' ,'+');
  return cal;}
 public static void Simplify_Test()
 {System.out.println("Simplify_Test:Input mathematical sentence");
  Scanner scn = new Scanner(System.in);
  String cal;
  cal = scn.nextLine();
  cal = Simplify_General(cal);
  System.out.println("Simplify_Test:Output=" + cal);}
 public static void main(String[] args)
 {Simplify_Test();}}
