17. why always "string args[ ]" coderanch.comWhen SUN created Java, they sat down and said "OK, what is the ONE best signature that we can use as a starting point for ALL applications". They decided that String can encompass all other data types as input. So they coded the compiler to always look for that particular method signature, and when found, use it to kick off the ... |
18. (String[] args) vs. (String args[]) coderanch.comIn main() there shouldn't be any difference. It only matters if you are making multiple declarations of arrays.

To be able to declare 2 String array references, I ... |

21. main(String args[]) versus main(String[] args) coderanch.comI just started a Java class and my instructor mentioned the second approach is preferred, BUT...

Thank you very much. |
22. what does (String[ ] args) mean? coderanch.comHi, Mike Well, any Java program needs a starting point. When a class has a method with the signature public static void main(String args[]) that means that class is elegible as an application starting point. For instance: public class Jedi{ public static void main(String args[]){ System.out.println("Hello Luke!"); } } After compiling your class with the javac.exe (in Windows) or the javac ... |
23. main ( String[] args) question coderanch.comAwesome info guys. I appreciate the time you guys take to answer silly questions like mine.

I didn't know if we could over ... |
24. String args[] vs. String[] args coderanch.comAs people have already said, it makes no difference to the behaviour, except in the case of declaring multiple variables in one line.

I think the "String args[]" version is ... |

27. Why main(String [] args) method must be public coderanch.comI can declare a class as non-public and packageless, and then run its main() method from the current directory. Why doesn't the main method run if i dont declare it as public? My question actually is but for the main method, the non-public class's method would actually not be accessible from other packages. So, from the current directory, since the non-public ... |
28. String[] arg Vs String... args coderanch.comThey are not 100% the same. String[] requires just that - an array of Strings. String... on the other hand, accepts both an array of Strings but also any number of Strings. As you can see, String... allows anything that String[] allows but not vice versa. Now, given that A) won't even compile, what do you think the answer is? |
29. Why do we give "String [] args" as an argument to main?? coderanch.comWhen you type "java MyClass", the JVM goes and looks for a method in MyClass with the signiature "public static void main (String [] args)" (although the specific name of the String array can be anything you want). If that method is not there, the JVM can't start up your program. However, it is perfectly valid to have a class that ... |
30. main(String[]args) coderanch.comit will not be used, but you still have to have it there. The jvm is EXPLICITLY looking for a method with that signiature. So if you wrote public static void main(){...} and didn't have the "String [] args", the jvm would not be able to find the 'entry point' into your program, and would complain. Note that the variable name ... |

48. why we use string args[] in void main() forums.oracle.comBecause that's roughly how C did it and Java is based on C.

49. Difference between (String....args) & (String [] args) forums.oracle.com"String... args" will declare a method that expects a variable number of String arguments. The number of arguments can be anything at all: including zero. "String[] args" and the equivalent "String args[]" will declare a method that expects exactly one argument: an array of strings. One difference that might not spring out from those observations is that in the second case ... |
50. Restart main(String args[]) forums.oracle.comDepends a bit. I think I'd go for a loop in main() so that "reset" terminates the current iteration through the loop, effectively restarting from the top of the loop. If terminating the current iteration is complicated, a possible hack is to throw an exception (declare your own exception subclass just for this purpose), catch in the loop in main and ... |
51. Why String args[] is mandatory in main() ? forums.oracle.comThe method signature is a combination of the name of the method and the parameters it takes. As such, two methods with the same name but different parameters are different -- indeed, this is what is called overloading a method. The JVM knows the signature of the main method to look for and run automatically. Allowing for a no-parameter version of ... |
