Question

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "MinMax" (without the quotation marks) that declares an array of doubles of length 5, and uses methods to populate the array with user input from the command line and to print out the max (highest) and min (lowest) values in the array. The methods that determine the max and min values may not use any built-in sort methods in Java. That is, you need to write the appropriate logic in those methods. NOTE: For this assignment and all future assignments that deal with methods, you should be calling the appropriate method to do the task indicated, rather than implementing the task logic in the main method itself.

Answer 1

inputs should should be taken from comman line arguments.. here i am taking inputs as 50 51 56 49 77

public class MinMax
{
public static void main(String[] args) //args is a array of string type
{
double[] array=new double[5]; //decalring array of doubles with size=5
for(int i=0;i<5;i++) //this loop used to convert strings to doubles
{
array[i]=Double.parseDouble(args[i]); //convert string to double and store it in array
}
double max_value=max(array); //calling max method and store return values in max_variable
double min_value=min(array); //calling min method and store return values in max_variable

System.out.println("Maximum value in the array is "+max_value); //printing max value
System.out.println("Maximum value in the array is "+min_value); //printing min value
}
  
  
  
static double max(double[] array)
{
double max=array[0]; //max is a variable intially hold the value array[0]
  
for(int i=0;i<5;i++) //this loop used to find max value
{if(array[i]>max) //if condition execute only if array[i]>max
{max=array[i];} //then change the max =array[i]
}
return max; //return max value
}
  
static double min(double[] array)   
{
double min=array[0]; //min is a variable intially hold the value array[0]
  
for(int i=0;i<5;i++) //this loop used to find min value
{if(array[i]<min) //if condition execute only if array[i]<min
{min=array[i];} //then change the min =array[i]
}
return min; //return min value
}   
}
