Help me please!!!

I want to compare between char array and char

Code:

---

//compare 2  char  with for loop
import java.util.Arrays;
class TestCheck{
        public static void main (String args[]){
                String str = "AB";
                int len,len2;
                char[] charArray = str.toCharArray();
                char inputChar;
                inputChar = 'A';
                System.out.print("\n");
                System.out.print("String is  "+str);
                System.out.print("\n");
                System.out.print("\n");
               
                for(int i = 0;i<charArray.length;i++){
                        System.out.println("char array is>>"+charArray[i]);
                }
                len = charArray.length;
                System.out.println("length of char array is>>"+len);
                System.out.print("\n");
               
                System.out.println("input char is>>  "+inputChar);
       
                ///////////////////////////////////////////////////////
                //compare two arrayList
               
                        for(int index = 0;index<charArray.length;index++){
                                        if(charArray[index] == inputChar){
                                                System.out.println("index  "+index+"  equals");
                                        }else{
                                                System.out.println("index  "+index+"  not equals");
                                        }
                        }
       
               
       
       
        }
}

This code no error,but I want to declare method Check() for compare charArray and inputChar
I 'm niebie in java.I want some advice for declare method Check.
Thanks.

Ok, you say you aren't getting any errors?

Do you get the right result when you run this?

Some thoughts:

you can have your str for your class and pass in your inputChar as an agument to your checkChar( char inputChar ) method, then loop through your string to test if inputChar == str.charAt(index) ... return index if found or -1 if not found ...

also - you assign the value of length to len ... why aren't you using len as your loop sentinel rather than accessing your arrayList every loop?

Thank for that.

Did what nspils post resolve your issue or do you still have questions?
