Answer / chandni jain

1. Using new keyword
This is the most common way to create an object in java.

MyObject object = new MyObject();

2. Using Class.forName()
If we know the name of the class & if it has a public
default constructor we can create an object in this way.

MyObject object = (MyObject)
Class.forName("subin.rnd.MyObject").newInstance();

3. Using clone()
The clone() can be used to create a copy of an existing object.

MyObject anotherObject = new MyObject();
MyObject object = anotherObject.clone();

4. Using object deserialization
Object deserialization is nothing but creating an object
from its serialized form.

ObjectInputStream inStream = new
ObjectInputStream(anInputStream );
MyObject object = (MyObject) inStream.readObject();

Answer / ravi jain

through

1) String s = "This is my Object";

2) String s1 = s.subString(1,8);

3) int[] arr = {12,45,12}; every array is an object.

4) String s2 = s + s1;

these all are also create new instances.

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; }
