delete() and deleteCharAt() method

delete() and deleteCharAt() method:

Java  provides us to StringBuffer the ability to delete character using the method delete() and deleteCharAt(). These method are shown here:

         StringBuffer delete(int startIndex,int endIndex)
         StringBuffer deleteCharAt(int loc)

Here is a small program to demonstrate these method:


package stringdemo;


public class DeleteDemo {
    public static void main(String[] args) {
        StringBuffer s= new StringBuffer("I love you");
        
        s.delete(2, 5);
        System.out.println("After delete:"+s);
        
        s.deleteCharAt(0);
        System.out.println("After deleteCharAt:"+s);
    }

}

OUTPUT:

After delete:I e you

After deleteCharAt: e you
