well thanks for not helping me out i helped my self

    Scanner gaba = new Scanner( System.in ); 
    String variable;
    System.out.print("Enter String:");
    variable = gaba.nextLine();
    SeparateGaba(variable);

    }
   public static void SeparateGaba(String str) 
    {
    String Catch_num = "";
    String Catch_let = "";
    String upper="";

    for (int i = 0; i < str.length(); i++) 
    {
           char a = str.charAt(i);
           if (Character.isDigit(a))

                 Catch_let = Catch_let + a;
           }     
    } 

    System.out.println("FIRST OUTPUT:"+Catch_num+Catch_let);

            if (cmp != 0) return cmp;
            return Character.compare(c1.charValue(), c2.charValue());
        }
        });

        StringBuilder sb = new StringBuilder(chars.length);
        for (char c : chars) sb.append(c);
        fal = sb.toString();
        System.out.println("SECOND OUTPUT= "+n+fal);
       /*GABA come on let seeeeeeeee*/
        try
        {
        for(int i=0;i<n.length();i++)
        {
            char a= n.charAt(i);

            System.out.print(a);

            for(int j=0; j<fal.length();j++)//1
            {
                char b = fal.charAt(j);
                if(j>=i)
                {   
                System.out.print(b);
                    break;
                }
            }
            }

           }
           catch(Exception e)
         {
       System.out.println("Your letter length should match with char len");
        }

       }
      }


       Enter String:14a5Bc
       FIRST OUTPUT:145aBc
       SECOND OUTPUT= 145aBc
       THE out put i was looking for --->1a4B5c

solved The requirement is, the output will print one number followed by a character then a number and so on
