Design pattern consists of two important words “Design” and “pattern”. Here design means software design and pattern means same type of problems (commonly occurring problems in software design). So, design pattern is a general, reusable solution to commonly occurring problems in software design. They are like ready-made blueprints that you can customize to solve a […]
