To sort long array in Java, use the Arrays.sort() method. Let’s say the following is our long array. long[] arr = new long[] { 987, 76, 5646, 96, 8768, 8767 }; To sort the above long array is an easy task in Java. Use the following method. Arrays.sort(arr); After that, print the array and you can see that it is sorted. for (long l : arr) { System.out.println(l); } The following is the complete example. Example Live Demo import java.util.*; public class Demo { public static ... Read More

The intersection of the two arrays results in those elements that are contained in both of them. If an element is only in one of the arrays, it is not available in the intersection. An example of this is given as follows − Array 1 = 1 2 5 8 9 Array 2 = 2 4 5 9 Intersection = 2 5 9 A program that demonstrates the intersection of two sorted arrays in Java is given as follows. Example Live Demo public class Example { public static void main(String args[]) ... Read More

A palindrome is a sequence that is same both forwards and backwards. The binary representation of a number is checked for being a palindrome but no leading 0’s are considered. An example of this is given as follows − Number = 5 Binary representation = 101 The binary representation of 5 is a palindrome as it is the same both forwards and backwards. A program that demonstrates this is given as follows. Example Live Demo public class Example { public static void main(String argc[]) { long num ... Read More

Before getting into picasso library example, we should know about picasso. Picasso is image processing library and developed by Square Inc.

To concatenate a String and some integer values, you need to use the + operator. Let’s say the following is the string. String str = "Demo Text"; Now, we will concatenate integer values. String res = str + 1 + 2 + 3 + 4 + 5; The following is the final example. Example Live Demo public class Demo { public static void main(String[] args) { String str = "Demo Text"; System.out.println("String = "+str); String res = str + 1 + 2 + 3 + 4 + 5; System.out.println(res); } } Output String = Demo Text Demo Text12345
