Write a Java Program to Clear the StringBuffer
PROGRAM: Java Program to Clear the StringBuffer
/*Java Program to Clear the StringBuffer*/
1: Java program to clear using StringBuffer using delete()
class Main {
public static void main(String[] args) {
// create a string buffer
StringBuffer str = new StringBuffer();
// add string to string buffer
str.append(“Java”);
str.append(” is”);
str.append(” popular.”);
System.out.println(“StringBuffer: ” + str);
// clear the string
// using delete()
str.delete(0, str.length());
System.out.println(“Updated StringBuffer: ” + str);
}
}
2: Clear the StringBuffer using setLength()
class Main {
public static void main(String[] args) {
// create a string buffer
StringBuffer str = new StringBuffer();
// add string to string buffer
str.append(“Java”);
str.append(” is”);
str.append(” awesome.”);
System.out.println(“StringBuffer: ” + str);
// clear the string
// using setLength()
str.setLength(0);
System.out.println(“Updated StringBuffer: ” + str);
}
}
3: Clear the StringBuffer by creating a new object
class Main {
public static void main(String[] args) {
// create a string buffer
StringBuffer str = new StringBuffer();
// add string to string buffer
str.append(“Java”);
str.append(” is”);
str.append(” awesome.”);
System.out.println(“StringBuffer: ” + str);
// clear the string
// using new
// here new object is created and assigned to str
str = new StringBuffer();
System.out.println(“Updated StringBuffer: ” + str);
}
}
