How to Find the Largest Palindrome in an Array in Java?
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 largest palindrome in an array. A number is said to be a palindrome number if after reversing the same number it is equal to the original number. 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 {857, 232, 1996991, 54545} After finding the largest palindrome of an array the result will be ...
Read MoreFind Count of Positive, Negative and Zero Elements in an Array in Java
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 the frequency of each element i.e how many times each element is occurring in an 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 {21, 10, 26, 21, 10, 33, 33, 20, 10, 21} After finding the frequency of each element of an array the result will be − Element | Frequency ------------------------ 21 | 3 10 | 3 ...
Read MoreFind the Equilibrium Index of an array in Java?
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 an index such that the sum of elements at lower indexes is equal to the sum of elements at higher indexes and hence that is called the equilibrium index of an array. In this article, you will see how to get the equilibrium index of an array by using Java programming language. Let’s explore. To Show You Some Instances Instance-1 Suppose the original array is {-4, 6, 2, 1, -7, 5, 3 ...
Read MoreHow to Find a Cumulative Sum Array in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data types. As per the problem statement we have to find a cumulative sum array which means array elements will be updated with the sum of the current element and all previous elements. To find the cumulative sum, the array must contain all numeric values. In this article, you will see how to find the cumulative sum of an array by using Java programming language. Let’s explore. To Show You Some Instances Instance-1 Suppose the original array is {2, 9, 3, 5, 1, ...
Read MoreHow to Check if the Given Arrays are Disjoint in Java?
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 check if the given arrays are disjoint. An array is said to be disjoint if two arrays have no element in common i.e. elements in the first array are not equal to elements in the second 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 two arrays are {13, 44, 11, 19, 3} and {7, 12, ...
Read MoreFind sum of two array elements index wise in Java
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 MoreFind Angle while Angle by similar Chord at center in Java
A circle is a round shape two-dimensional diagram that has no corners. Every circle has an origin point and every point on the circle maintains an equal distance from the origin. The distance between the origin and a point in a circle is known as the 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 the diameter of the circle. Basically, the diameter is double of the length of the radius. The chord of ...

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. Arc of the circle refers to ...
Read MoreCapitalize last letter and Lowercase first letter of a word in Java
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 MoreCheck Average of Odd Elements or Even Elements are Greater in Java
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 all even and odd numbers in a given array and compare them to see which one is greater. 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 {14, 49, 55, 67, 72, 82} After finding average of sum of even and ...
