[SOLVED] indexing an element in an array help!

Code:

---

if(input.equals(choices[1])){
              accountNum = JOptionPane.showInputDialog("What is your account number?");
              result = getAccountIndex(accountNum, accountNumber[i]);
              makeDeposit(accountNumber[i],accountBalance[i], creditLimit[i]);
            }
            if(input.equals(choices[2])){
              accountNum = JOptionPane.showInputDialog("What is your account number?");
              result = getAccountIndex(accountNum, accountNumber[i]);
              makeWithdrawal(accountNumber[i],accountBalance[i], creditLimit[i]);
            }

I seem to be getting an error on the line "result = ...." on both 'if' statements that says:

Error: getAccountIndex(java.lang.String,java.lang.String[]) in A5Q1ummadhoa cannot be applied to (java.lang.String,java.lang.String)

I think I may be overthinking the situatuation.

Code:

---

public static int getAccountIndex(String key, String accountNumber[]){
      int result = -1;
     
      for(int i=0;i<accountNumber.length;i++){
       
        if(key.equals(accountNumber[i])){
          return i;
        }
        else System.out.println("Invalid account number.");
      }
      return result;
    }

you are passing in 2 strings as arguments. your method is expecting a string and an array of strings.
