Question

Write a program that uses an array of high temperatures for your hometown from last week (Sunday - Saturday). Write methods to calculate and return the lowest high temperature (minimum) and a method to calculate and return the highest high temperature (maximum) in the array. You must write YOUR ORIGINAL methods for minimum and maximum. You MAY NOT use Math class methods or other library methods. Write an additional method that accepts the array as a parameter and then creates and returns a new array with all the same values as the original plus 10. (num +=10)

java pseudocode and source code help?

Answer 1

Created methods with appropriate comments are given for your understanding in the below code.

CODE:

package temperature;
public class Temperature {
//Method to find the minimum temperature.
public static double lowHighTemperature(double temperature[])
{
double min;
//Assigning maximum value of double to variable min so as to make comparison of minimum easy.
//Because any double value will going to be less than it's maximum value.
min = Double.MAX_VALUE;
//for-each loop to find the minimum temperature.
for(double i: temperature){
if(i<min)
min = i;
}
//returning the minimum temperature.
return min;
}
//Method to find the maximum temperature.
public static double highestHighTemperature(double temperature[])
{
double max;
//Assigning minimum value of double to variable max so as to make comparison of maximum easy.
//Because any double value will going to be greater than it's minimum value.
max = Double.MIN_VALUE;
//for-each loop to find the maximum temperature.
for(double i: temperature){
if(i>max)
max = i;
}
//returning the maximum value.
return max;
}
//Method to add 10 to each element of the array and returning that modified arrya.
public static double[] addTemperature(double temperature[])
{
for(int i=0;i<temperature.length;i++)
temperature[i] += 10;
return temperature;
}
public static void main(String[] args) {
//Initializig the temperature with temperature of the 7 days of week.
double temperature[] = {30.5,20.5,22.5,23,40.5,15.5,35};
//Calling the appropriate function to return the lowest temperature
//of last 7 days and assiging it to a minTemp variable.
double minTemp = lowHighTemperature(temperature);
//Calling the appropriate function to return the highest temperature of
//the last 7 days and assigning it to maxTemp variable.
double maxTemp = highestHighTemperature(temperature);
//Calling the appropriate function to add 10 to each element of the array
//and returned value is assigned to newTemperature array.
double newTemperature[] = addTemperature(temperature);
//Printing the returned values
System.out.println("The minimum temperature of the last 7 days is:"+minTemp);
System.out.println("The maximum temperature of the last 7 days is:"+maxTemp);
System.out.println("The temperature array after adding 10 to each temperature is:");
for(int i=0;i<newTemperature.length;i++)
System.out.print(newTemperature[i]+" ");
}
  
}

CODE SCREENSHOT:

package temperature; public class Temperature { //Method to find the minimum temperature. public static double lowHighTemperature (double temperature []) { double min; //Assigning maximum value of double to variable min so as to make comparison of minimum easy. //Because any double value will going to be less than it's maximum value. min = Double.MAX VALUE; //for-each loop to find the minimum temperature. for (double i: temperature) { if(i<min) min = i; } //returning the minimum temperature. return min; } //Method to find the maximum temperature. public static double highestHighTemperature (double temperature []) { double max; //Assigning minimum value of double to variable max so as to make comparison of maximum easy. //Because any double value will going to be greater than it's minimum value. max = Double.MIN VALUE; //for-each loop to find the maximum temperature. for (double i: temperature) { if(i>max) max = i; } //returning the maximum value. return max; //Method to add 10 to each element of the array and returning that modified arrya. public static double [] addTemperature(double temperature []) { for (int i=0;i<temperature.length;i++) temperature [i] += 10; return temperature; }

public static void main (String[] args) { //Initializig the temperature with temperature of the 7 days of week. double temperature [] = {30.5, 20.5,22.5, 23, 40.5,15.5, 35}; //Calling the appropriate function to return the lowest temperature //of last 7 days and assiging it to a minTemp variable. double minTemp = lowHighTemperature (temperature); //Calling the appropriate function to return the highest temperature of //the last 7 days and assigning it to maxTemp variable. double maxTemp = highestHighTemperature (temperature); //Calling the appropriate function to add 10 to each element of the array //and returned value is assigned to newTemperature array. double newTemperature [] = addTemperature (temperature); //Printing the returned values System.out.println ("The minimum temperature of the last 7 days is:"+minTemp); System.out.println ("The maximum temperature of the last 7 days is:"+maxTemp); System.out.println ("The temperature array after adding 10 to each temperature is:"); for (int i=0;i<newTemperature.length;i++) System.out.print (newTemperature [i]+" ");

CODE OUTPUT:

run: The minimum temperature of the last 7 days is:15.5 The maximum temperature of the last 7 days is:40.5 The temperature array after adding 10 to each temperature is: 40.5 30.5 32.5 33.0 50.5 25.5 45.0 BUILD SUCCESSFUL (total time: 0 seconds)
