1) Write a Java program that finds Sum, Average & Max. Number of Array using Inheritance.

 

class Inher_1

{

int[]arr={10,20,5,25,30,1000};

}

class Inher_2 extends Inher_1

{

public void menu(int k)

{

switch(k)

{

case 1:sum();break;

case 2:avg();break;

case 3:max();break;

default:System.out.println("test");break;

}

}

public void sum()

{

int sum=0;

for(int i=0;i<arr.length;i++)

sum=sum+arr[i];

System.out.println("sum:"+sum);

}

 

public void avg()

{

int sum=0;

for(int i=0;i<arr.length;i++)

sum=sum+arr[i];

System.out.println("avg:"+sum/arr.length);

}

public void max()

{

int max=arr[0];

for(int i=0;i<arr.length;i++)

{

if(arr[i]>max)

max=arr[i];

}

System.out.println("max:"+max);

}

}

class Inher

{

public static void main(String ad[])

{

Inher_2 ob=new Inher_2();

ob.menu(1);

ob.menu(2);

ob.menu(3);

}

}

Output:

sum:1090

avg:181

max:1000
