जावा - अस्थैतिक चर सदस्य

इस क्रमादेश में तीन क्लास kaksha में तीन सदस्य चरों को घोषित किया गया है। इन्हे कन्स्ट्रक्टर के माध्यम से प्रारंभिकरण किया गया है। फलन show_data के माध्यम से निर्गत को स्क्रीन पर मुद्रित किया गया है। मेन फलन में kaksha का अभिलक्ष्य बनाकर show_data फलन को निष्पादित किया गया है। इस क्रमादेष में सभी सदस्य अस्थैतिक है।

जावा क्रमादेश

-------------------------------------

class kaksha

{

int admid;

String name;

String batch;

public kaksha( int p_admid, String p_name, String p_batch )

{ admid = p_admid;

name = p_name;

batch = p_batch;

}

public void show_data()

{

System.out.println("\n Admission ID -> " + admid);

System.out.println("\n Name -> " + name);

System.out.println("\n Batch -> " + batch);

}

class main_class_2109

{

public static void main(String args[])

{

kaksha bca_2021= new kaksha(41730,"Prachi","2018-21");

kaksha bca_2022 = new kaksha(41702,"Ritika","2019-22");

kaksha bca_2023 = new kaksha(43460,"Ankita","2020-23");

bca_2021.show_data();

bca_2022.show_data();

bca_2023.show_data();

}

क्रमादेश में उपयोग किये गये

अस्थैतिक चर एवं फलन की स्मृति संरचना

छात्र स्पष्ट रूप से देख सकतें है कि प्रत्येक अभिलक्ष्य ने स्वयं के चरों एवं फलनों हेतु स्मृति में व्यक्तिगत स्थान है।
