which of the following is/are true regarding the string array provided as a parameter to the main method in java
Answers
Answer:
Those inputs are stored in this String args array. Because if also we are not passing any argument value while running the main method then also its working fine. It creates an empty string, when we are not passing any values to string arg[]. Where else in case of other data type we have to pass some values...
which of the following is/are true regarding the string array provided as a parameter to the main method in java is given below
Explanation:
1.Java main method is the entry point of any java program. Its syntax is always public static void main(String[] args) . You can only change the name of String array argument, for example you can change args to myStringArgs .
2.The String[] args parameter is an array of Strings passed as parameters when you are running your application through command line in the OS. The java -jar command will pass your Strings update and notify to your public static void main() method.
3.String[] args in Java is an array of strings which stores arguments passed by command line while starting a program. All the command line arguments are stored in that array.
4.The main method in Java should have a String[] args as an argument because the language specification compels you to. When you don't give a String[] args in your main method it will not throw any error but you will not be able to run your class. This is because there will be no entry point for your class.
5.The main() Method. A Java application is a public Java class with a main() method. The main() method is the entry point into the application. The signature of the method is always: public static void main(String[] args) Command-line arguments are passed through the args parameter, which is an array of String s.
6.Java program's main method has to be declared static because keyword static allows main to be called without creating an object of the class in which the main method is defined. ... In this case, main must be declared as public , since it must be called by code outside of its class when the program is started.
7.The main() method must be called from a static method only inside the same class. The main() method must be passed the String[] args while calling it from somewhere else. Calling the main() method will lead to an infinite loop as the memory stack knows to run only the main() method.
