    How do we create 1000 object
    One way would be to use a loop.

    What will be the memory size required?
    Depends on the size of an object.

    You can't do it directly. Java has several methods that give approximations of memory usage that could be used. See the API doc for the Runtime class.

    Question JAVA

    if the size of one object is 110 bytes and there are 1000 such objects then how can we efficiently call a method using this object so that minimum memory is required?
