Question

I am trying to make a code that can detect mistakes in the user input with respect to String array stored in program.

Lets say Program contains “The quick brown fox jumps over the lazy dog”

if the user enters “The quick brown is name over Jumps the lazy”

The program tells the user that you have made 5 Mistakes. But my code is not working correctly for the above mentioned user input. What is my code lacking to detect such mistakes. Here is the code:

public void checkTextCompleted()
{
    String input= text.getText();
    int temp=array[0],mistakes=0;

    if(input.length()==data.length()) {
        text.setEditable(false);
        text.setFocusable(false);

        for(int j=0;j<dataWords;j++) {
            int x = input.indexOf(data.substring(array[j]-temp, array[j]-1));

            System.out.println(x);
            if(x != -1) {
                String subs = input.substring(x, input.length());

                if(data.contains(subs)) {
                    break;
                } else {
                    mistakes++;
                    if(j!=0)
                        temp=array[j-1];
                    else
                        temp=array[j];
                }
            }
            else
                mistakes++;
        }
        JOptionPane.showMessageDialog(null,"You have made "+mistakes+" mistakes" , "Typing Test Completed", JOptionPane.OK_OPTION);
    }
}

The array[] contains the positions at which the space is detected in Program builtin String(data) and dataWords contains the number of words in program builtin String(data). User input is stored in “input”

What is my code lacking to detect the above mentioned problem?

Note:
if one word is wrong and the remaining string after it is correct, mistake will be 1 other wise, next mistake will be detected on the same principal.

Cant you shrink your code by this simple logic ?

String[] expectedSentenceA = "The quick brown fox jumps over the lazy dog".split(" ");
String[] inputStringA = inputString.split(" ");
int diff=  expectedSentenceA.length-inputStringA.length;
if(diff>0) {
    System.out.println("You have missed " + diff + " word(s)..!!!");
} else if (diff < 0) {
    System.out.println("Found " + diff + " excess word(s)..!!!");
}else {
   ArrayList<String> mistakeWords= new ArrayList();
   for(int i=0;i<expectedSentenceA.length;i++) {
    if(!expectedSentenceA[i].equals(inputStringA[i])){
        mistakeWords.add(inputStringA[i]);
    }
   }
   JOptionPane.showMessageDialog(null,"Total Mistakes ["+mistakeWords.size()+"] are " + mistakeWords);
}
