        Scanner input=new Scanner(System.in);   

        String sent;
        String string;
        String part;

        System.out.println("Enter a sentence:");

This case can have 2 cases.
1) Delete all the occurence of given word
2)Delete only a given occurence(mostly first) of given word

You have to split the input sentence using String.split() method. It will result into a array of Sring, containing all your words. Now compare all your words with the given input word. If a match is not there append the word into a StringBuilder along with a space. This will remove all the occuerence. If you want to delete a particular instance. Count the no of instance and break from the loop accordingly
