String 1: This is Exercise 1 String 2: This is Exercise 2 "This is Exercise 1" is less than "This is Exercise 2" ... Write a Java program to compare two strings lexicographically, ignoring case differences.

Strings, one of the most common objects used in Java programming, are essentially sequences of characters. As an example, the string "Scaler" contains the following characters: "S", "c", "a", "l", "e", and "r". You can either create a string by using String Literal or by using the NEW keyword.

December 10, 2024 - Problem: Check if two strings are permutations of each other.

(solution) Write an efficient Java/C/Python/Ruby program to return the duplicate characters from given String, for example, if given String is "C++" then your program should print "+" Similarly, if the input is "Java and JavaScript" then your program should print "J", "a" and "v". You can ignore the case for finding duplicates. If you notice there is a pattern to solve these duplicate characters problem.

5. Write a Java program to compare two strings lexicographically Two strings are lexicographically equal if they are the same length and contain the same characters in the same positions View Solution

Since strings are represented by double quotes, the compiler will treat "This is the " as the string. Hence, the above code will cause an error. To solve this issue, we use the escape character \ in Java. For example,

November 23, 2022 - If you’re implementing conditional flow for strings, you can use if-else conditions and you can use switch case if you are using Java 7 or higher versions. Learn more about Java switch case string. You’ll need to use recursion to find all the permutations of a string. For example, the permutations of AAB are AAB, ABA and BAA.

Basic string problems -- no loops. Use + to combine Strings, str.length() is the number of chars in a String, str.substring(i, j) extracts the substring starting at index i and running up to but not including index j. New videos: String Introduction, String Substring helloName H makeAbba H ...

Each challenge has a problem statement that includes sample inputs and outputs.

September 1, 2008 - Discover a variety of Java String examples that demonstrate key string manipulation techniques and operations.

For example, if String is "Java" then the program should print "a". Bonus points if your program is robust and handles different kinds of input e.g. String without duplicate, null or empty String etc.

public class ComputeResult { public static void main(String[] args) { String original = "software"; StringBuilder result = new StringBuilder("hi"); int index = original.indexOf('a'); /*1*/ result.setCharAt(0, original.charAt(0)); /*2*/ result.setCharAt(1, original.charAt(original.length()-1)); /*3*/ result.insert(1, original.charAt(4)); /*4*/ result.append(original.substring(1,4)); /*5*/ result.insert(3, (original.substring(index, index+2) + " ")); System.out.println(result); } }

October 7, 2025 - Strings are widely used for storing and processing textual data in programs. Here is a complete list of Java String practice programs divided into basic and advanced categories:

January 8, 2024 - An anagram is a word formed by rearranging the letters of another given word, for example, “car” and “arc”. To begin, we first check whether both the Strings are of equal length or not. Then we convert them to char[] array, sort them, and then check for equality. Java 8 really simplifies aggregation tasks like these:
