Conversion from String to StringBuffer and StringBuilder

    Here in this context We can directly pass String class object to StringBuffer and StringBuilder class constructors. As String class is immutable in java, so for editing a string, we can perform same by converting it to StringBuffer or StringBuilder class objects. 

Example.java

package java8s;

public class Example {

          public static void main(String[] args) {

                  

                   String str="SILAN";

                  

                   //Conversion from String object to StringBuffer

                   StringBuffer sb1=new StringBuffer(str);

                  

                   System.out.println(sb1);

                  

                   sb1.reverse();

                   System.out.println(sb1);

                  

                   //Conversion from String object to StringBuilder

                    StringBuilder sb2=new StringBuilder(str);

                   sb2.append("Technology");

                  

                   System.out.println(sb2);

                                     

          }

}

Output:

SILAN 

NALIS

SILANTechnology
