package org.kodejava.example.lang;
public class StringBuilderDelete {
public static void main(String[] args) {
StringBuilder lipsum = new StringBuilder("Lorem ipsum dolor sit amet, " +
"consectetur adipisicing elit.");
System.out.println("lipsum = " + lipsum.toString());
//
// We'll remove a substring from this StringBuilder starting from the
// first character to the 28th character.
//
lipsum.delete(0, 28);
System.out.println("lipsum = " + lipsum.toString());
//
// Removes a char from the StringBuilder. In the example below we remove
// the last character.
//
lipsum.deleteCharAt(lipsum.length() - 1);
System.out.println("lipsum = " + lipsum.toString());
}
}
