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.")};
