In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to get all the triplets in the array whose sum is equal to a specific number. Here triplets refer to any three elements of the array which meet a specific condition. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {3, 4, 25, 6, 13, 9}. ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the sum of two different arrays with respect to index and store it into a third array. Suppose a1[] is first array, a2[] is second array and a3[] is third array, then sum of a1[] and a2[] should be stored in a3[] i.e. a1[0] + a2[0] = a3[0] a1[1] + a2[1] = a3[1] a1[2] + a2[2] = a3[2] and so on. Let’s start! Note − Two array lengths must be the ... Read More

In Java, Array is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find count of positive numbers, negative numbers and zero present in the given array. Any number which is greater than zero that is called as positive number, if the number is less than zero then that is negative number else the given number is a zero. Let’s see how we can do it by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {2, 0, -1, 4, -6} In the ... Read More

In Java, Array is a non-primitive data type which stores values of similar data type. As per the problem statement we have to detect the elements which are repeating in an array and print its frequency. An array can contain duplicate values as well. So, the number of times an element is present in an array, that is called frequency of the element in the array. Let’s see how we can do it by using the Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {2, 3, 5, 4, 3, 1, 3, 2, 1, 2, ... Read More

A circle is a round shape two-dimensional diagram which has no corners. Every circle has an origin point and every point on the circle maintains equal distance from the origin. The distance between the origin and a point in a circle is known as Radius of the circle. And similarly, if we draw a line from one edge to another edge of the circle and the origin is held in the middle of it, that line is known as diameter of the circle. Basically, the diameter is double of the length of the radius. Chord of the circle refers to ... Read More

String is a sequence of character values. In Java, Strings are considered as objects. We have a String class provided by Java for creating and manipulating strings. We have to convert the first letter of the word to lowercase and last letter of the word to uppercase. In this article we will see how the first and last letter can be converted into lower and upper case respectively. Let’s explore. To Show You Some Instances Instance-1 Suppose the input string is “Hello” After converting the first letter to lower and last letter to capital, the new string will be “hellO” ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the sum of elements which is even and sum of elements which is odd in an array and compare their sum and check which one is smaller. A number is said to be even if it is divisible by 2 else it is called an odd number. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. ... Read More
