Thank's!
public class TeacherAssistant {
public static String validatedFieldName(String fieldName) {
// These things should be verified:
// 1. Member fields must start with an 'm'
// 2. The second letter in the field name must be uppercased to ensure camel-casing
// NOTE: To check if something is not equal use the != symbol. eg: 3 != 4
String mFieldName = fieldName ;
if(mFieldName != fieldName){
throw new IllegalArgumentException(" ");
};
return fieldName;
}

2,758 PointsHi!
The first task that you showd achieve is "1. Member fields must start with an 'm'"
So, your first if condition showd look something like this:
//charAt method returns the character that is passed in the index number
if(!fieldName.charAt(0) == 'm ') { throw new IllegalArgumentException("The first letter showld be m"); }
The second task is "2. The second letter in the field name must be uppercased to ensure camel-casing".
For this I created a variable to store the second character of the incoming variable. It showd be at the top of the method:
char secondLetter = fieldName.charAt(1);
Your second if show be like this:
if(!Character.isUpperCase(secondLetter)) { throw new IllegalArgumentException("The second letter must be upperCase"); }
Hope it helps. Sorry for my english.
