Table Writing

Write Java Program Which take input integer and Show its Table.

import java.util.Scanner;

public class arrays {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);

System.out.println("Enter Integer for its Table");

int nums = input.nextInt();  

          for (int i= 0; i < 10;i++ )

          {

         System.out.println(nums + "  *" +" " +(i+1) +" = "+(nums*(i+1)));

         }

       }

}

Replacing Array Elements

Replacing Array Elements

import java.util.Scanner;

public class arrays {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);

int num[]  = new int [5];

int num2[] = new int [5];

int sum[] = new int [5];

System.out.println("Enter Integer for 1st Array");

 

         for (int i= 0; i < 5;i++ )

         {

        num[i]=input.nextInt();

       

         }

         System.out.println("Enter Integer for 2nd Array");

         for (int k=0;k<5;k++)

         {

        num2[k]=input.nextInt(); 

         }

         System.out.println("Sum of both arrays is");

         for (int s=0;s<5;s++)

         {

        sum[s]=num[s]=num2[s];

        System.out.println(num[s]);

         }

}

}

Given an array of ints length 5, return the sum of all the elements.

Source Code

import java.util.Scanner;

public class arrays {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);

int num[]  = new int [5];

int num2[] = new int [5];

int count =0;

System.out.println("Enter  1st array Integer");

          for (int i= 0; i < 5;i++ )

         {

         

        num[i]=input.nextInt();

          count = num[i]+count;

         }

          System.out.println("Sum of Array is "+count);

}

}

Given 2 arrays of ints, a and b, return true if they have the same first element or they have the same last element. Both arrays will be length 1 or more.

Source Code 

import java.util.Scanner;

public class arrays {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);

int num[]  = new int [5];

int num2[] = new int [5];
  int count=0;

 System.out.println("Enter  1st array Integer");

         for (int i= 0; i < 5;i++ )

         {num[i]=input.nextInt();

           }

         System.out.println("Enter 2nd array Integer");

         for (int k=0;k<5;k++)

         { num2[k]= input.nextInt ();

         }

     for (int m =0; m < 5; m++)

{if ((num[0] ==num2[0]) || (num[4]==num2[4]))

{count++;

}

}

if (count > 0)

{

System.out.println("True");

}

}

}

Sorting of Arrays

Bubble Sorting of Arrays  

import java.util.Scanner;

public class Arrays

{

public static void main (String [] args)

{ Scanner input = new Scanner (System.in);

int lengths =5;

int nums[] = new int [lengths];

for (int i=0; i < lengths; i++)

{

System.out.println("Enter integer num  # :" + (i+1));

nums[i] = input.nextInt();

}

for (int k=0; k < lengths; k++)

{

for (int m=0; m < lengths-1; m++)

{

if (nums[m] > nums[m+1])

{

int temp = nums[m+1];

nums [m+1] = nums[m];

nums[m] = temp;

}

}

}

for (int i =0; i <lengths; i ++)

{

System.out.println("Sorted integer are  # :" + nums[i]);

}

}

}

Arrays Addition

How to Add Two Arrays In Java. 

import java.util.Scanner;

public class arrays {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);

int num[]  = new int [5];

int num2[] = new int [5];

int sum[] = new int [5];

System.out.println("Enter Integer for 1st Array");

 for (int i= 0; i < 5;i++ )

       {num[i]=input.nextInt();}

         System.out.println("Enter Integer for 2nd Array");

         for (int k=0;k<5;k++)

         {num2[k]=input.nextInt();  }

         System.out.println("Sum of both arrays is");

         for (int s=0;s<5;s++)

         {sum[s]=num[s]+num2[s];

        System.out.println(sum[s]);

         }

Storing Values in Arrays in Java

Write a Java Program Which Write and Read Value in Array.

import java.util.Scanner;

public class JavaArrays

{

public static void main (String [] args)

{

Scanner input = new Scanner (System.in);

int [] nums = new int [10];

for(int i =0;i<10;i++)

{

System.out.println("Enter Integer # :" + (1+i));

nums[i] = input.nextInt();

}

System.out.println("Your Integer are");

for(int k=0;k<10;k++)

{

System.out.println(nums[k]);

}

}

}
