k greater than or equal to 6
class demo { public static void main(String[] args) { if(args.length == 2) { System.out.println(args[0] + args[1]); } else { System.out.println("Usage: demo Str1 Str2"); } }
Static keyword when used with a method, specifies that this method belongs to the class and not a particular instance of the class (a.k.a object of the class) Ex: public class StaticTest { public static String getAuthorName() { return "Anand"; } } Here getAuthorName is the static method and it can be accessed without instantiating an object of the class StaticTest. You can access this method as: String authorName = StaticTest.getAuthorName();
The main method can be declared as either of the below: public static void main(String[] args) or public static void main(String args[])
class NumberString{private string _value;private static int getIntValue(string aString) {return int.Parse(aString);}public static NumberString operator +(NumberString n1, NumberString n2) {return new NumberString(getIntValue(n1._value) + getIntValue(n2._value));}public NumberString(int n) { _value = n.ToString(); }}
Remember that strings are objects. You can use the String.equals method to determine equality, and use the ! (not) operator to test for inequality. public static boolean notEquals(String str1, String str2) { return !str1.equals(str2); }
class demo { public static void main(String[] args) { if(args.length == 2) { System.out.println(args[0] + args[1]); } else { System.out.println("Usage: demo Str1 Str2"); } }
class MyClass { // Declare a static method to return the square of a number. public static int getSquare(final int n) { return n*n; } public static void main(String[] args) { // Call the static method to find 1522 System.out.println( MyClass.getSquare(152) ); } }
Implement the following method: public static int stringLength(String s) { if(s.equals("")) return 0; else return stringLength(s.substring(0)) + 1; }
public class Primes { public static void main(String[] args) { for(int i = 2; i < 100; i++) { if(isPrime(i)) { System.out.println(i); } } } public static boolean isPrime(int n) { if(n 0) return false; } return true; } } }

public class S{public static void main(String[]a){String o="public class S{public static void main(String[]a){String o=%c%s%c;System.out.printf(o,34,o,34);}}";System.out.printf(o,34,o,34);}}
It would actually make no difference. The presence of the keywords during the declaration of the main method is important and not the order. so a static public void main(String[] args) would just compile and run perfectly fine just like public static void main(String[] args)
