Programming Example
static block in java,we can execute a program without main() method
Study this program carefully to understand the logic, output, and explanation in a structured way.
class OnlyStaticBlock{
static{
System.out.println("static block is invoked");
}
}depend ok jdk version :
static block is invoked
Error: Main method not found in class OnlyStaticBlock, please define the main method as:
public static void main(String[] args)
Press any key to continue . . .
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
