count of a character (after removal) is more than 2 in the stringif(text.length()-text.replaceAll(text.charAt(0)+"","").length()>2){ctr++;// Increment the counter if duplicate characters are found more than twice}// Remove all occurrences of the first character from the string 'text...
Split the string into a character array. Iterate over the character array. For each iteration, use the character as theMapkey,and check if the same character is present in the map, already. If the map key does not exist, the character has been encountered for the first time. Store it i...

In this quick tutorial, we’ll illustrate how we cancheck if aStringis containing at least one of each of the following: uppercase letter, lowercase letter, digit or special character in Java. 2. Using Regular Expressions One of the ways to perform our check is by using regular expressions...
The test passes if we execute it. So the check methods solved the problem. 4. Checking Each Character Although we successfully addressed the problem using the converting and comparing approach, such asinput.equals(input.toUpperCase()), this method may not be optimal when dealing with long input...
