Here is an example of comparing two strings for equality without considering their case sensitivity. To do this we can use equalsIgnoreCase() method of the String class. Let’s see an example below: package org.kodejava.basic; public class EqualsIgnoreCase { public static void main(String[] args) { String uppercase = "ABCDEFGHI"; String mixed = "aBCdEFghI"; // To compare […]
package org.kodejava.lang; public class StringBuilderInsert { public static void main(String[] args) { StringBuilder alphabets = new StringBuilder("abcdfghopqrstuvwxyz"); System.out.println("alphabets = " + alphabets); // |a|b|c|d|f|g|h|i|…. // 0|1|2|3|4|5|6|7|8|… // // From the above sequence you can see that the index of the string is // started from 0, so when we insert a string in the fourth […]
This example demonstrate you how to use the StringBuilder delete(int start, int end) and deleteCharAt(int index) to remove a substring or a single character from a StringBuilder. package org.kodejava.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 = […]
