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

        StringBuffer sb = new StringBuffer("Java is a programming language : ");

        // use delete(int spos , int epos) it will delete all characters 
        // lies between index1 and index2.

        // Display result after implementing delete(0,9)
        System.out.println("The result will be after implementing method delete(0,9) is :" + sb.delete(0, 9));

        sb = new StringBuffer("Java Support OOPS Concept");

        // use delete(int spos , int epos) it will delete all characters 
        // lies between spos and epos

        // Display result after implementing delete(17,25)
        System.out.println("The result will be after implementing method delete(17,25) is :" + sb.delete(17, 25));
    }
}

Output

D:\Programs>javac StringBufferClass.java
D:\Programs>java StringBufferClass
The result will be after implementing method delete(0,9) is : programming language :
The result will be after implementing method delete(17,25) is :Java Support OOPS
