What can be the possible solution for 2nd step

I am converting the 2nd character to uppercase but to make it upper case in the string firldName

TeacherAssistant.java 
public class TeacherAssistant {

  public static String validatedFieldName(String fieldName) {
    // These things should be verified:
    // 1.  Member fields must start with an 'm'
    char temp=fieldName.charAt(1);
    if ( fieldName.charAt(0)!='m'){
    throw new IllegalArgumentException("Member fields must start with an m");
    }
    // 2.  The second letter in the field name must be uppercased to ensure camel-casing


    if ( !Character.isLetter(temp)){
      throw new IllegalArgumentException("Please enter a letter");
    }
   temp= Character.toUpperCase(temp);

    // NOTE:  To check if something is not equal use the != symbol. eg: 3 != 4
    return fieldName;
  }

}
