Examples of Java and z3 Programs
DESCRIPTION
- Synchronous Readline for interactively running to have a conversation with the user via a console.
- Original codes in java as examples.
- z3 codes with z3 notations are shown below the java code.
EXAMPLES
Codes for Example
1. Check Odd/Even
Java Code:
https://beginnersbook.com/2014/02/java-program-to-check-even-or-odd-number
import java.util.Scanner;
class CheckEvenOdd
{
public static void main(String args[])
{
int num;
System.out.println("Enter an Integer number:");
//The input provided by user is stored in num
Scanner input = new Scanner(System.in);
num = input.nextInt();
// If number is divisible by 2 then it's an even number
// else odd number*/
if ( num % 2 == 0 )
System.out.println("Entered number is even");
else
System.out.println("Entered number is odd");
}
}
z3 code:
var readlineSync = require('readline-sync');
console.log("Starting");
var temp;
var num = readlineSync.question("Enter any number: ");
( num % 2 == 0 )::
{console.log(num + " is an even number")},
{console.log(num + " is an odd number")};
2. Sum of Array
Java Code:
https://beginnersbook.com/2014/01/java-program-to-sum-the-elements-of-an-array
import java.util.Scanner;
class SumDemo{
public static void main(String args[]){
Scanner scanner = new Scanner(System.in);
int[] array = new int[10];
int sum = 0;
System.out.println("Enter the elements:");
for (int i=0; i<10; i++)
{
array[i] = scanner.nextInt();
}
for( int num : array) {
sum = sum+num;
}
System.out.println("Sum of array elements is:"+sum);
}
}
z3 code:
var readlineSync = require('readline-sync');
console.log("Starting");
var k;
k = readlineSync.question("Number of elements: ");
var numbers = new Array(k);
//Enter numbers using comma
var num = readlineSync.question("Enter the elements: ");
var temp = num.split(",");
for (var i=0; i<k; i++)
{
numbers[i] = temp[i];
}
var sumofarray = SUM(numbers);
console.log("Sum:" +sumofarray);
3. Linear Search
Java Code:
https://beginnersbook.com/2014/04/java-program-for-linear-search-example
import java.util.Scanner;
class LinearSearchExample
{
public static void main(String args[])
{
int counter, num, item, array[];
//To capture user input
Scanner input = new Scanner(System.in);
System.out.println("Enter number of elements:");
num = input.nextInt();
//Creating array to store the all the numbers
array = new int[num];
System.out.println("Enter " + num + " integers");
//Loop to store each numbers in array
for (counter = 0; counter < num; counter++)
array[counter] = input.nextInt();
System.out.println("Enter the search value:");
item = input.nextInt();
for (counter = 0; counter < num; counter++)
{
if (array[counter] == item)
{
System.out.println(item+" is present at location "+(counter+1));
/*Item is found so to stop the search and to come out of the
* loop use break statement.*/
break;
}
}
if (counter == num)
System.out.println(item + " doesn't exist in array.");
}
}
z3 code:
var readlineSync = require('readline-sync');
console.log("Starting");
var k;
k = readlineSync.question("Number of elements: ");
var numbers = new Array(k);
//Enter numbers using comma
var num = readlineSync.question("Enter the elements: ");
var temp = num.split(",");
var item = readlineSync.question("Enter the search value: ");
for (i = 0; i < k; i++)
{
(temp[i]-item== 0)::
{
console.log(item+" is present at location "+(i+1));
break;
};
}
(i-k ==0)::
{console.log(item + " doesn't exist in array.")};
