Get the Most Frequent Element 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 detect which element is repeated maximum times in an array for maximum number of times 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. And the element whose frequency is more that is the most frequent element in the array. Let’s see how we can do it by using the Java programming ...
Read MoreHow to Find the Union of Two Arrays 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 union of two arrays. Union refers to joining together whereas union of arrays refers to the new array combining all unique elements from the input arrays. 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 first array is {0, 3, 5, 6, 9, 1}. And the second array is {1, 2, 6, 10, 8, 7}. ...
Read MoreFind the Middle Element 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 the element which is present in the middle of the array. If the array contains odd number of elements, then you will get one element present at the exact middle of the array. If the array contains even number of elements, then you will get two elements present at the middle of the array. In this article, you will see how to get the middle element of an array by using Java ...
Read MoreHow 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 ...
