Class is a template of object. It tells compiler this is how the object would be(like a design).
Object is actual implementation. It is an instance of the class. In simple words, class doesnt occupy any memory whereas Object does.

for (int i = 0; i < s.length(); i++) {
String s2=""+s.charAt(i);
if(i==0){
s3+=s2.toUpperCase();
System.out.println("@i==0 "+s3);
}
else if (s.charAt(i)==' ') {

i++;
s2+=s.charAt(i);
s3+=s2.toUpperCase();

Class: It is logical entity which contain logic for the application . class is like a blueprint which decide the object creation .
Object: Object is a physical entity which represent the memory allocation .
Eg: if we have created a blueprint for building then we can create multiple building at different location ,so these creation of biulding is called as the object.

CLASS:-
1.Class is a keyword which is used to create user defined data types or Non-primitive datatypes.
2.Class is used to represent blueprint of an object and its logical entity.
3.So, when we create a class which represents the blueprint of an object, a blueprint class should not have a main method according to java convention.
4.The blueprint class is also known as business logic class.

OBJECT:-
1.In java object is a block of memory created during runtime.
2.According to Object Oriented Programming object is considered as a mirror image of a blueprint of the class.
3.Class is considered as a logical entity where as objects are considered as real entities.
4.According to java convention a blueprint class will never have a main method.
