Example of StringBuilder in Java
February 21, 2013
StringBuilder has come in java since jdk 1.5. StringBuilder is not synchronized. It cannot be used in multi-threaded
environment. StringBuffer can be used in multi-threaded environment. StringBuilder has the methods append, insert and appendCodePoint etc.
appendCodePoint can add character ASCI value with the string as
sb.appendCodePoint(90);
package com.concretepage;
public class StringBuilderTest {
public static void main(String... args) {
StringBuilder sb = new StringBuilder("Hello");
//appends the string
sb.append(" World");
//insert the string at specified place
sb.insert(6, " Great_ ");
//90 ASCI of Z, it is appended at the end
sb.appendCodePoint(90);
System.out.println(sb);
//gets capacity of string builder object
int c = sb.capacity();
System.out.println(c);
}
}
