Question

a. Write a method that receives (a reference to an array of integers and returns the number of odd values in the array that are between 20 and 35 (inclusive) or greater than 65 (also b. Write a single Java expression in Java that corresponds to the following formula: 2 (y3 – 5) - VZ)10)

Answer 1

#source code for first one:

import java.util.Scanner;

import java.lang.*;

class Sample{

public static int oddNumCount(int data[]){ //function declaration

int count=0;

for(int i=0;i<data.length;i++){ //iterate over each element in the array

if(data[i]%2==0){ //check element is odd or not

if(data[i]>65 || (data[i]>=20 && data[i]<=35 )){ //f element is odd than it chech condion

count=count+1; //increment the count value by 1

}

}

}

return count;

}

public static void main(String args[]){

int data[]={34,56,78,98,37,49,27,28,29,30}; //array intialization

int oddcount=oddNumCount(data); //call the method

System.out.println("Odd number count:"+oddcount); //print the oddcount in the array

}

}

#second one source code such as formula expression:

import java.util.*;

import java.lang.*;

class Sample{

public static void main(String args[]){

double y=2,z=3; //here y and z values are initialized

double val=Math.pow(((Math.pow(y,3)-5)/Math.pow((1-Math.sqrt(z)),10)),2); //ecpression in single line

System.out.println("Value:"+val); //output the value

}

}

#source code along with output:

1 2 4 5 import java.util.*; import java.lang. *; class Sample { public static void main(String args[]) { double y=2, Z=3; //here y and z values are initialized double val=Math.pow(((Math.powly,3)-5)/Math.pow((1-Math.sqrt(z)),10)),2); //ecpression in single line System.out.println("Value: "+val); //output the value 8 } } Terminal Ox File Edit View Search Terminal Help user@user-Latitude - 3490:-/Desktops javac Sample.java user@user-Latitude - 3490:-/Desktop$ java Sample Value:4606.998046858244 user@user-Latitude - 3490:-/Desktop
