How 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 ...

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 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 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 ...
