A block inside of a method is just code that gets executed as part of the method which you can use as to limit scope of some variable(s). https://beginnersbook.com/2013/04/java-static-class-block-methods-variables/ https://www.javatpoint.com/instance-initializer-block http://www.the...
Space Complexity:The space complexity of creating the static map in the static method is O(n), where n is the number of key-value pairs in the map. Approach 3: Direct Initialization Define the static map as a class variable. Initialize and populate the map directly at the point of declar...
Another approach to initializing static fields is by using static methods. These methods can be called explicitly or within a static block to perform initialization tasks. By encapsulating the initialization logic in a static method, you can improve code readability and separate concerns. publicclassMy...
Java Static Import - The static import feature of Java 5 facilitate the java programmer to access any static member of a class directly. There is no need to qualify is with the class name.
