explain main method in java
Main() method is starting point of execution for all java applications.
public static void main(String[] args) {}
String args[] are array of string objects we need to pass from command line
arguments.
Every Java application must have atleast one main method.
public : “public” is an access specifier which can be used outside the class.
When main method is declared
public it means it can be used outside class.
static : To call a method we require object. Sometimes it may be required
to call a method without the
help of object. Then we declare that method as static. JVM calls the main()
method without creating
object by declaring keyword static.
void : void return type is used when a method does’nt return any value .
main() method does’nt return
any value, so main() is declared as void.
