Find 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 ...
Read MoreCheck if Array is Free From 0 and Negative Number 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 and confirm the array is free from 0 and negative numbers. Let us say that an array contains 0 or a negative element then the result should pop up that "Array contains 0 or a negative number." Otherwise, the result should be "Array doesn’t contain 0 or a negative number." Note − The array must be an integer array. Let’s explore the article to see how it can be done by using ...
Read MoreArrange Negative Array Elements Before Positive Elements 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 arrange all elements of array such that negative elements are present before positive elements. If a number is greater than 0 then it is called as positive number, if less than 0 then it is called as negative 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. To Show You Some Instances Instance-1 Suppose the ...
Read MoreJAVA Program to Replace Element of Integer Array with Product of Other Elements
Array of Integers refers to an array where all the elements are of Integer type. It is alsocalled an Integer array. As per the problem statement we have to create an Integer array and display the array elements where all the array elements are the product of other elements of the array. In this article, we will see how to replace array elements by the product of other array elements by using Java programming language. To show you some instances − Instance-1 int arr[] = { 2, 3, 1, 4, 6 } At Index-0 value will be = 3 * ...

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 ...
Read MoreJava Menu Driven Program to Perform Basic String Operations
String refers to a sequence of characters. In Java Strings are objects. To create and manipulate strings Java provides the String class. String class has many inbuilt methods which are used for different purposes. We will perform a few basic string operations by using inbuilt String methods. replace() Method: It replaces a specified character in the given string. concat() Method: It appends another string to the end of one string. length() Method: It returns the length of the given String. Equals() Method: It checks whether two strings are equal or not. In this article, we will see some basic ...
