How to Know If Two Convex Regular Polygons have Same Centre or Not in Java?
A polygon is a 2-dimensional closed shape that has at least 3 sides. Depending on the number of sides, relationships of the sides and angles, and other characteristics, polygons can be classified under different names like triangles, squares, and quadrilaterals. The convex polygon definition explains that one is a polygon whose angles are all less than 180 degrees each. That also means that the vertices, the point where two sides meet, all point outward from the centre of the shape. In this article, we will find if two convex regular polygons have same centre or not. We will take two ...
Read MoreHow to Confirm If Given Four Points Form a Square in Java?
A square is a two-dimensional shape which has four sides of equal length. The opposite sides of a square are parallel to each other and all four interior angles are right angles with diagonal of equal length. In this article we will check how to confirm if given four points form a square. We will be given a square with four points i.e. A, B, C, D as shown in the figure − We need to check from these points that if they form a square or not. To check this it should satisfy the following condition − ...
Read MoreReplace Negative and Positive Matrix Elements with 0 & 1 in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Here we have given a matrix which contains set of elements including both positive and negative numbers and as per the problem statement we have to replace negative numbers with 0 and positive numbers with 1. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given matrix =-21 22 -23 24 -25 26 ...
Read MoreHow to Print Lower Triangular Matrix in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Triangular Matrix − A square matrix is called as a triangular matrix if all the elements above or below the diagonal of that matrix are zeros. Lower- Triangular Matrix − A square matrix is called as a Lower- Triangular Matrix if all the elements above the diagonal of that matrix are zeros. Here we have to print the lower triangular matrix. Let’s start! To show ...
Read MoreHow to Find Sum of Matrix Elements in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Here we have given a matrix which contains set of elements and as per the problem statement we have to find out the sum of all the elements present inside the matrix. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given matrix =21 22 23 24 25 26 27 28 29 Sum ...
Read MoreHow to Display an Identity Matrix in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. An identity matrix is a square matrix where all the elements of the main diagonal (i.e., the diagonal from the top-left to the bottom-right corner) are 1, and all the other elements are 0. It is denoted by the symbol "I" or "In", where "n" represents the size of the matrix. The identity matrix is important in linear algebra because it acts as the ...
Read MoreHow to Check if the Matrix is Diagonal Matrix in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. A matrix having non-zero elements only in the main diagonal (running from the upper left to the lower right) is called as diagonal matrix. As per the problem statement we have to a matrix and we have to check whether that given matrix is a diagonal matrix or not. Let’s deep dive into this article, to know how it can be done by using Java ...
Read MoreForm Equation of Circle from Given Radius and Centre in Java
A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant. In this article we will check how to form the equation of circle from given radius and centre. We will be given a circle with centre i.e (x1, y1) and radius r. We need to form the equation of circle from given radius and centre. The equation of the circle is given by formula − $$\mathrm{(x-x1)^2\:+\:(y-y1)^2\:=\:r^2}$$ Now after expanding and arranging the equation we get − $$\mathrm{(x)^2\:–\:(2*x1*x)\:+\:(y)^2\:-\:(2*y1*y)\:=\:(r)^2\:-\:(x1)^2\:-\:(y1)^2}$$ Let’s start! To show you ...
Read MoreHow to find total area when two rectangles overlap each other in Java?
A Rectangle is a four sided-polygon, with opposite side equal and having all the internal angles equal to 90 degrees. In this article we will check how to find total area when two rectangles overlap each other. We will be given with two rectangle having length and breadth. Also we will we given with intersecting length and width of the two rectangles as shown in the figure − To find the total area of a rectangle we basically add areas of two rectangles. This includes the intersecting part twice, so we subtract the area of intersecting part. Total ...
Read MoreFind Column Which is Having Maximum 0’s in a Binary Matrix in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. A binary matrix is a matrix of 0s and 1s, where each element can only be one of two possible values. Here we have given a binary matrix which contains set of binary elements and as per the problem statement we have to find the column which is having maximum number of 0’s. Let’s start! To show you some instances Instance-1 Given binary matrix =1 ...
