Here you will get java program to find union of two arrays. For example we have two sorted arrays a1[] = {2, 3, 5, 11} and a2[] = {4, 7, 9} then union of a1 and a2 will be {2, 3, 4, 5, 7, 9, 11}. A Java program for finding union of two arrays …
import java.util.Scanner; //import Scanner class in our program class demo { public static void main(String…s) { int i,n,large,small; Scanner sc=new Scanner(System.in); //used to read from keyboard System.out.print(“Enter number of elements:”); n=sc.nextInt(); int a[]=new int[n]; System.out.print(“nEnter elements of Array:”); for(i=0;i<n;++i) a[i]=sc.nextInt(); large=small=a[0]; for(i=1;i<n;++i) { if(a[i]>large) large=a[i]; if(a[i]<small) small=a[i]; } System.out.print(“nSmallest Element:”+small); System.out.println(“nLargest Element:”+large); } }
In this tutorial you will learn about difference between compiler and interpreter i.e. compiler vs interpreter. We know that computers can only understand machine language which is in binary format. But we write in natural programming language (like C, Java etc). So there must be something which converts these programming instructions into machine understandable instructions. …
A linked list can be reversed by changing the direction of the pointer, iteratively. Algorithm for reversing the linked list Let us take three pointer variables P, q and r. P references the linked list reversed so far, q points to the linked list to be reversed and r points to the next node of …
There has been an overwhelming importance given to custom web designs off-late. Even if a company got its website developed by the de facto best web designers in town, eventually, they want the “custom” power in their hands. The ability to make changes on the fly, as and when they want, is what has driven …
this holds the reference of current object. Observe below example: class demo { int x=10; void show(int x,demo d1) { System.out.println(this.x); System.out.println(d1.x); System.out.println(x); } public static void main(String…s) { demo d1=new demo(); d1.show(20,d1); } } Output: 10 10 20 In Java by default …

Have you ever thought about executing your java program without main() method? If you write a program without main() and compile it then it will compile successfully. But as you execute the program it will show an error that Main method not found in the class. JVM verify the code before its execution. JVM checks …
