Question

IN JAVA

Array Operations

Write a program with an array that is initialized with test data. Use any primitive data type of your choice. The program should also have the following methods:

• getTotal: This method should accept a one-dimensional array as its argument and return the total of the values in the array.
• getAverage: This method should accept a one-dimensional array as its argument and return the average of the values in the array.
• getHighest: This method should accept a one-dimensional array as its argument and return the highest value in the array.
• getLowest: This method should accept a one-dimensional array as its argument and return the lowest value in the array.

Demonstrate each of the methods in the program.

Answer 1

Program in Java -

public class arrayOperations{
  
static int getTotal(int[] a){
int sum=0;
for(int i=0;i<a.length;i++)
sum = sum+a[i];
return sum;
}
  
static float getAverage(int[] a){
int sum=0;
for(int i=0;i<a.length;i++)
sum = sum+a[i];
float average=sum/a.length;
return average;
}
  
static int getHighest(int[] a){
int max=a[0];
for(int i=0;i<a.length;i++)
if(a[i]>max)
max=a[i];
return max;
}
  
static int getLowest(int[] a){
int min=a[0];
for(int i=0;i<a.length;i++)
if(a[i]<min)
min=a[i];
return min;
}
  

public static void main(String []args)
{
int a[]=new int[]{55,66,11,33,99,2,4,6,88,77};
int Sum = getTotal(a);   
float Average = getAverage(a);
int Highest=getHighest(a);
int Lowest=getLowest(a);
System.out.println("Sum of array values="+Sum);
System.out.println("Average of array values="+Average);
System.out.println("Highest value in array="+Highest);
System.out.println("Lowest value in array="+Lowest);
  
}
}

The output of the Program -
