public class StringBufferExample {

// The main() method is the entry point of every Java application.

public static void main(String[] args) {

// Create a StringBuffer object.

StringBuffer stringBuffer = new StringBuffer("Java");

// Display the original StringBuffer.

System.out.println("Original StringBuffer : " + stringBuffer);

// Append text to the StringBuffer.

stringBuffer.append(" Programming");

System.out.println("After append() : " + stringBuffer);

// Insert text at the specified index.

stringBuffer.insert(5, "Core ");

System.out.println("After insert() : " + stringBuffer);

// Replace characters from index 5 to 9.

stringBuffer.replace(5, 9, "Advanced ");

System.out.println("After replace() : " + stringBuffer);

// Delete characters from index 5 to 14.

stringBuffer.delete(5, 14);

System.out.println("After delete() : " + stringBuffer);

// Reverse the StringBuffer.

stringBuffer.reverse();

System.out.println("After reverse() : " + stringBuffer);
