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. If the absolute value of the diagonal element in a matrix is larger than or ... 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 ... Read More

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 ... 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. A binary matrix is a matrix of 0s and 1s, where each element can only ... 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 ... 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 ... 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 we have to subtract an element “1” to each matrix element. Let’s ... Read More

In Java, A primitive type (i.e., int, double, float, etc.) is a basic data type that is built into the language and is not an object. Primitive types have a fixed size and can be used directly in calculations and operations. A wrapper object is nothing but an object ... Read More

In Java, Object is a parent class of all the classes. So, we can directly assign a string to an object as each class is internally a child class of the Object class. A string is generally considered a data type and is often implemented as an array data structure ... Read More

In Java, smaller datatype can be converted to bigger datatype. Here, we will see how to convert int datatype to double datatype. The int data type is a 32-bit signed two's complement integer. Its value-range lies between - 2, 147, 483, 648 (-2^31) to 2, 147, 483, 647 (2^31 -1). ... Read More
