System- public final class System extends Object

The System class contains serveral useful class
fields and methods.it cannot be instantiated

out-

The out variable in the System class refers to (points
to) an instance of the PrintStream class (a PrintStream
object) which is automatically instantiated when the System
class is loaded into the application.

println()-the println() methods in class PrintStream.

System.out.prinln("HI DILIP ");

This statement invokes the println() method of an object of
the PrintStream class which is referred to (pointed to) by
the variable named out which is a class variable of the
System class.

public class Test { public static void main(String[] args) { int countA = 0; int countB = 0; int countC = 0; int countD = 0; int countE = 0; int countF = 0; int countG = 0; int countH = 0; int countI = 0; int countJ = 0; int countK = 0; int countL = 0; int countM = 0; int countN = 0; int countO = 0; int countP = 0; int countQ = 0; int countR = 0; int countS = 0; int countT = 0; int countU = 0; int countV = 0; int countW = 0; int countX = 0; int countY = 0; int countZ = 0; } } Can anybody tell me any alternate solution(like loop or something) to automate this initialization process. Ex:- for(char chr='A';chr<='Z'; chr++) { (int) String "count"+chr = 0; }
