Java Program easy points! Most of code written

A split method also needs to be added of the form:

split( class delimeter, mystring s)

HERE IS THE CODE I ALREADY HAVE AND IS CORRECT JUST METHODS NEED TO BE ADDED

package mystring;

public class MyString {

//Character array to hold string
private char[] chars;

//myString constructor
public MyString(char[] chars) {
this.chars = new char[chars.length];
System.arraycopy(chars, 0, this.chars, 0, chars.length);
}

//Return the string
public char[] toChars() {
return chars;
}

//Return the string length
public int length() {
return chars.length;
}

//Return character at index
public char charAt(int index) {
return chars.charAt();
}

//Return substring
public MyString substring(int begin, int end) {
return myString.substring(start, Math.min(start + length, myString.length());
  
return new MyString(sub);
}

//Return string in lower case
public MyString toLowerCase() {

return new MyString(lower);
  

}
}

package mystring;

public class TestString {
  
public static void main(String[] args) {

MyString s = new MyString(new char[] {'T', 'e', 's', 't'});
System.out.println(s.toChars());
System.out.println("Test length is " + s.length());
System.out.println("The character at position 2 is " + s.charAt(2));
System.out.println("Test lower case method:");
MyString t = s.toLowerCase();
System.out.println(t.toChars());
System.out.println("Test substring method:");
MyString u = t.substring(2, 4);
System.out.println(u.toChars());
}
  
}

CODE NEEDS TO BE FULL AND COMPLETE FOR FULL POINTS PLEASE!

Explanation / Answer

package mystring;
public class MyString
{
   //Character array to hold string
   private char[] chars;
   //myString constructor
   public MyString(char[] chars)
   {
       this.chars = new char[chars.length];
       System.arraycopy(chars, 0, this.chars, 0, chars.length);
   }

   //Return the string
   public char[] toChars()
   {
       return chars;
   }

   //Return the string length
   public int length()
   {
       return chars.length;
   }

   //Return character at index
   public char charAt(int index)
   {
       //Get character at index
       return chars[index-1];
   }

   //Return substring
   public MyString substring(int begin, int end)
   {
       //Convert the character array to string
       String str=String.valueOf(chars);
       //Get substring from str
       String substring=str.substring(begin, end);
       //convert the str back to character array
       char[] charArray=substring.toCharArray();
       return new MyString(charArray);
   }

   //Return string in lower case
   public MyString toLowerCase()
   {
       //Convert the character array to string
       String tempString=String.valueOf(chars);
       //Call toLowerCase on tempString
       String lowerCase=tempString.toLowerCase();
       //convert the str back to character array
       char[] lowerCaseArray=lowerCase.toCharArray();
       return new MyString(lowerCaseArray);

   }
}

package mystring;

public class TestString {

   public static void main(String[] args) {

       MyString s = new MyString(new char[] {'T', 'e', 's', 't'});
       System.out.println(s.toChars());
       System.out.println("Test length is " + s.length());
       System.out.println("The character at position 2 is " + s.charAt(2));
       System.out.println("Test lower case method:");
       MyString t = s.toLowerCase();
       System.out.println(t.toChars());
       System.out.println("Test substring method:");
       MyString u = t.substring(2, 4);
       System.out.println(u.toChars());
   }

}

Sample run:

Test
Test length is 4
The character at position 2 is e
Test lower case method:
test
Test substring method:
st
