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 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 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
Being a web developer, it's important to have a solid understanding of 3D transformations and how to apply them to child elements. Transforming child elements can be a bit tricky, as we'll need to make sure that the transformations of the parent element are preserved. CSS 3D transforms create depth and visually interesting elements on the web page using perspective. In this article, we will learn how to transform child elements and preserve 3D transformations. We will learn different methods to transform the child elements in HTML. Different Methods to Transform Child Elements Preserve the 3D Transformations To transform 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 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. 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
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 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 {{3, 1, 2}, {2, 5, 9}, {6, 3, 10}}; After subtracting the element “1” by given matrix, the result index will ... 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 representation of a primitive type. For example, the Integer class is a wrapper object for the int primitive type. Wrapper objects are instances of classes and have methods that can be called, while primitive types do not. However, using wrapper objects requires more memory than using primitive types, ... 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 of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. The object data type is also known as non-primitive or reference data type; these are not predefined ones; instead, we need to create them. Let’s deep dive into this article, to know how it ...

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). The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the Floating-Point Types, Formats, and Values section of the Java Language Specification. Let’s deep dive into this article, to know how it ... Read More
In Java, Date can be converted Timestamp by using Timestamp class. Timestamp class is present in sql package. Date only store date value whereas timestamp stores both date and time value. The TIMESTAMP data type is used for values that contain both date and time parts. TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC. 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 input date is written on 05/01/2023. Then corresponding Timestamp is “2023-01-05 20:37:54.832”. Instance-2 ... Read More
