- We can Covert String to string builder in two ways
- Using constructor of StringBuilder(String s)
- Using append method of StringBuilder
- Lets see a java program to convert java String object to StringBuilder using constructor of StringBuilder class.
#1: Java program to convert string to StringBuilder using constructor of StringBuilder class.
- package com.instanceofjava;
- /**
- * @author www.Instanceofjava.com
- * @category interview programs
- *
- * Description: Java Program to convert String to StringBuilder
- *
- */
- public class StringBuilderDemo {
- public static void main(String[] args) {
- String str="java";
- StringBuilder sb = new StringBuilder(str);
- String s = sb.toString();
- System.out.println(s);
- StringBuilder stebldr= new StringBuilder("convert string to stringbuilder");
- String st = stebldr.toString();
- System.out.println(st);
- }
- }
Output
- java
- convert string to stringbuilder
#2: Java program to convert string to StringBuilder using append method of StringBuilder class.
- package com.instanceofjava;
- /**
- * @author www.Instanceofjava.com
- * @category interview programs
- *
- * Description: Java Program to convert String to StringBuilder
- *
- */
- public class StringBuilderDemo {
- public static void main(String[] args) {
- StringBuilder sb = new StringBuilder();
- sb.append("Java convert string to StringBuilder ");
- System.out.println(sb);
- String str= "Convert string to Stringbuilder" ;
- sb.append(str);
- System.out.println(sb);
- }
- }
Output
- Java convert string to StringBuilder
- Java convert string to StringBuilder Convert string to Stringbuilder
- We can Convert StringBuilder to String by using toString() method of StringBuilder class.
- How to convert StringBuilder to String in java.
#3: Java program to convert string to StringBuilder using append method of StringBuilder class.
- package com.instanceofjava;
- /**
- * @author www.Instanceofjava.com
- * @category interview programs
- *
- * Description: Java Program to convert StringBuilder to String
- *
- */
- public class StringBuilderDemo {
- public static void main(String[] args) {
- StringBuilder sb = new StringBuilder();
- sb.append("Java convert StringBuilder to string");
- String str=sb.toString();
- System.out.println(str);
- String s= "Convert Stringbuilder to string " ;
- sb.append(s);
- String st=sb.toString();
- System.out.println(st);
- }
- }
Output
- Java convert StringBuilder to string
- Java convert StringBuilder to stringConvert Stringbuilder to string
