ARRAY:
array is a userdefined datatype in almost all languages.
array is able to store only one type of values.
syntax:array a1[10];in c
array a1=new array[10];in c++ &java
that means array can store fixed no of values,ofcourse we
can dynamically allocate memory in java but we can't extend
the size.
ARRAYLIST:
arraylist is not supported in c
it is also a type of array in which we can extend size
dynamically.
syntax:
ArrayList ar=new ArrayList();
where ArrayList is a 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; }
