I am writing a program that will read a text file and calculate number of words/characters etc. That bit works fine, but I am struggling on how to find a specific word(in this case 'The' - I also need it to be able to ignore case)

each time I search for ' the ' (leading and follwing space) I get an error 'unclosed character literal'

Please suggest where I am going wrong (I'm a beginner, so please go easy on the techical talk!)

Code:
 (I haven't included keyboard3.java or text file)

import javax.swing.JOptionPane;


	public class MSShowPane2{
		char choice; 
		private String s;
		String CurrentString = s;
		int countspaces = 0;

		int AverageWordLength = 0;

		int numberofCharacters2 = 0;
		int NumberofCharacters2 = 0;
		int CountCommas = 0;
		int CountWords = 0;
		int countwords = 0;
		int num=0;
		int countthe = 0;
		//int CheckThe = 0;
		String testString = CurrentString;

	public void LoadText1() { 
		s = Keyboard3.readTextFile("Shirley.txt");
		System.out.println("Shirley By Bronte Sisters ... Loaded ");

	public void AverageWordLength() {

		}

	public void CountWords() { 
		//Assuming each word is followed by a space.
		String CurrentString = s;
		for (int i =0;i < CurrentString.length() ;i++ )
		{if (CurrentString.charAt(i) == ' ')
		{countspaces++;}}
		int CountWords = countspaces +1;
		System.out.println("Number of Spaces: " + countspaces);
		System.out.println("Number of Words: " + CountWords);
		}

	public void CheckThe() {
