Object Oriented Programming-1 (Lab Sesion-6)

• Explore below three classes of java

1. String Class
2. StringBuffer Class
3. StringBuilder Class

Learn how String can be constructed using all these classes. Write a sample program to create String with all three classes.

Solution :

Code :

package .vscode;

public class Compare_String { 

    public static void string(String s1) { 

        S1 = s1 + “OrientedProgram”; 

    } 

    

    public static void stringbuilder(StringBuilder s2) { 

        S2.append(“OrientedProgram”); 

    } 

    public static void stringbuffer(StringBuffer s3) {

        S3.append(“OrientedProgram”); 

    } 

    public static void main(String[] args) { 

        String s1 = “Object”; 

        String(s1);  

        System.out.println(“String: “ + s1); 

        StringBuilder s2 = new StringBuilder(“Object”);        stringbuilder(s2); 

        System.out.println(“StringBuilder: “ + s2); 

        StringBuffer s3 = new StringBuffer(“Object”); 

        Stringbuffer(s3); 

        System.out.println(“StringBuffer: “ + s3); 

    } 

}
