Examples of using the find command include searching for all files in the current directory, searching for all files owned by a particular user, and searching for files modified after a certain date. 34. Software Design Patterns Software Design Patterns are reusable solutions to common software problems. They provide a way to structure code, making it easier to maintain and extend over time. With these patterns, developers can focus on the problem, not the code, and create more efficient applications. Each pattern is a proven solution to a specific problem, and can be used to improve the overall design of a system. 35. Methods in Java Methods in Java are used to perform specific tasks within a Java program. They are declared with a name, a list of parameters, and a block of code that contains the logic of the method. Methods can be defined within a class, or outside of it in a separate file. Methods can be either static or non-static, and can have a return type or be void. When calling a method, the parameters must match the method declaration. Java methods are a powerful tool for organizing and manipulating data. 36. Pair Class in Java Pair Class in Java is a powerful utility class that allows developers to store two objects of different types in a single unit.
