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 ... Read More

Matrices are nothing but it’s more than a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. As per the problem statement the task is to find the product of sum of all elements in first row and last row. 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 Suppose the original matrix is{{15, 5, 9}, {4, 14, 16}, {7, 8, 19}}; After finding product of sum ... Read More

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. Upper- Triangular Matrix − A square matrix is called as a Upper ... Read More

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 number of odd elements and even elements in each row of a matrix. Let’s start! To show you some instances Instance-1Given matrix = 21 22 23 24 25 26 27 28 29 Row 1 has 2 odd elements and 1 even element Row 2 has ... Read More

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 the multiplication of diagonal elements. In this article we will see, how it can be done by using Java programming language. To show you some instances Instance-1Given matrix = 21 22 23 24 25 26 27 28 29 Main diagonal elements are: 21, 25 and 29 Anti-diagonal ... Read More

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 point i.e (x, y), radius r and centre i.e (x1, y1). We need to form the equation of circle from given radius and centre. The equation of the circle is given by formula − $$\mathrm{(x\:-\:x1)^2\:+\:(y\:-\:y1)^2\:=\:r^2}$$ Where, (x, y) is a point. (x1, y1) is centre. And r ... Read More

The number system is of four types: Binary, Octal, Decimal and Hexadecimal with base value 2, 8, 10 and 16 respectively. The base value depends on the number of digits contained by number system. For example, hexadecimal number system contains 16 digits i.e. 0 to 9 and A to F. Hence, its base is 16. In this article, we will discuss the binary and decimal number systems. Also, we will make java programs to convert decimal to binary numbers. Binary and Decimal number system Binary number system Binary number system works in the form of 0s and 1s. Since ... Read More
