POinheritance example for mean and median
text
Body
copied!<p>I am working on mean, median in java. I have created a program but I am not able to properly implement inheritance on it. In my code, for every inherited class object, its asking input. </p> <p>I want input to be taken only once and then using inheritance mean and mode to be calculated. Kindly suggest. </p> <pre><code>import java.io.*; import java.util.*; class A { int a[]; int no; A() { System.out.println("Number of elements for an array : "); Scanner in1 = new Scanner(System.in); no = in1.nextInt(); a = new int[no]; for(int i=0; i<no; i++) { System.out.println("Enter elements : "); Scanner in2 = new Scanner(System.in); a[i] = in2.nextInt(); } } void sort() { int tmp; for(int i=0; i<no-1; i++) { for(int j=i+1; j<no; j++) { System.out.println("a[i] : " + a[i] + " a[i+1] : " + a[i+1]); if (a[i]>a[j]) { tmp = a[i]; a[i] = a[j]; a[j] = tmp; } } } } void display() { System.out.println(); for(int i=0; i<no; i++) { System.out.println(a[i]); } } } class B extends A { int tot = 0; float mean; void get_mean() { System.out.println("no : " + no); for(int i=0; i<no; i++) { tot += a[i]; } System.out.println("tot : " + tot); mean = (float) tot/no; System.out.println("mean : " + mean); } } class C extends A { void median() { float median; if(no%2==0) { int middle = no/2; median = (float)((a[middle] + a[middle/2])/2); } else { median = a[(no/2)]; } System.out.println("median : " + median); } } class test { public static void main (String arg[]) throws IOException { B obj1 = new B(); obj1.get_mean(); C obj2 = new C(); obj2.sort(); obj2.median(); } } </code></pre>
