How to compare StringBuffer object to String object in java?


Description:

The below example shows how to compare StringBuffer object with String object. String object provides contentEquals() method to compare content with a StringBuffer object.


Code:
package com.myjava.string;

public class MyStringComp {

    public static void main(String a[]){
    
        String c = "We are comparing the content with a StringBuffer content";
        StringBuffer sb =
			new StringBuffer("We are comparing the content with a StringBuffer content");
        /**
         * We can use contentEquals() method to compare content with a StringBuffer.
         * It returns boolean value.
         */
        if(c.contentEquals(sb)){
            System.out.println("The content is equal");
        } else {
            System.out.println("The content is not equal");
        }
        StringBuffer asb =
			new StringBuffer("You cannot compare the content with a String content");
        if(c.contentEquals(asb)){
            System.out.println("The content is equal");
        } else {
            System.out.println("The content is not equal");
        }
    }
}

Example Output

Knowledge Centre
Interface and its usage
Interface is similar to a class which may contain method's signature only but not bodies and it is a formal set of method and constant declarations that must be defined by the class that implements it. Interfaces are useful for declaring methods that one or more classes are expected to implement, capturing similarities between unrelated classes without forcing a class relationship and determining an object's programming interface without revealing the actual body of the class.
Famous Quotations
Never argue with a fool, onlookers may not be able to tell the difference.
