Java Programming Exercises, Practice, Solution
Java is the foundation for virtually every type of networked application and is the global standard for developing and delivering embedded and mobile applications, games, Web-based content, and enterprise software. With more than 9 million developers worldwide, Java enables you to efficiently develop, deploy and use exciting applications and services.
The best way we learn anything is by practice and exercise questions. Here you have the opportunity to practice the Java programming language concepts by solving the exercises starting from basic to more complex exercises. A sample solution is provided for each exercise. It is recommended to do these exercises by yourself first before checking the solution.
Hope, these exercises help you to improve your Java programming coding skills. Currently, following sections are available, we are working hard to add more exercises .... Happy Coding!
Note: If you are not habituated with Java programming you can learn from the following :

Java for students
Java is a popular and widely used programming language. It was originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems’ Java platform. The language’s syntax has much in common with C and C++, but its object model is simpler and has less low-level facilities. Undoubtedly, one of Java’s strong points is an automatic memory management. The developer determines when objects are created, but it’s a runtime task to free memory, when objects are no longer in use.
Java is a good choice for students, either studying computer science or related subjects. Here we present a collection of Java tutorials helping students to get started with the language, setup a development environment and master the basics.
- Setting up Eclipse: Java’s popular IDE
- Hello world program line by line
- Variables, types, loops, if statement
- Practice. Developing "number guessing game" step by step
- True/false, boolean type, logical connectives
- Switch statement
- Practice. Menu-driven "bank account" application
- Hello world
- Number guessing game
- Strings comparison
- Sum of digits of a number
- Convert String to int and int to String
- Print command-line arguments
- Switch-operated text menu
- Decimal to binary converter
Algorithms and data structuresOne can not imagine modern programming language, like Java, without integrated algorithms and data structures. Java has extensive utilities library (java.util), which contains hundreds of algorithms and data structures. But it is still important to have basic knowledge on the subject and general ideas of how things work. We would recommend the following resource on the subject: algorithms and data structures. It gives illustrated explanations of many algorithms and data structures. Articles are supplemented with implementations in Java and C++. You might start with the quicksort article to learn the most popular sorting algorithm, applied in practice.
