Early detection of any disease, especially cancer, is very crucial for the treatment phase. One such effort made in this direction is the use of machine learning algorithms to detect and diagnose skin cancer with the help of a machine learning framework like Tensorflow. The traditional method of cancer detection is quite time-consuming and requires professional dermatologists. However, with the help of TensorFlow, not only can this process be made fast, but more accurate and efficient. Moreover, people who do not get timely access to doctors and dermatologists, can use this meanwhile. Algorithm Step 1 − Import the ... Read More
The power of machine learning has enabled us to predict rainfall with several algorithms, including Random Forest and XGBoost. There are no best algorithms for predicting rainfall, every algorithm has its advantages and disadvantages. The Random Forest is efficient with small datasets, while the XGboost is efficient with large datasets. In the same way, we can categorise other algorithms based on the needs of our projects. Our goal here is to build a predictive machine-learning model of rainfall based on Random Forests. Algorithm Import all the required libraries such as Pandas, Numpy, Sklearn, and matplotlib. Load the ... Read More
Like in many other sectors, predictive analysis is quite helpful in the finance and insurance sector as well. Using this machine learning technique, we can find out useful information about any insurance policy and therefore save huge sums of money. Here, we will be using this approach of predictive analysis for a medical insurance dataset. The problem statement here is that we have a dataset of some people with certain attributes. Using machine learning in Python, we have to find out relevant information from this dataset and also have to predict the insurance price a person will have to ... Read More
Machine learning is a subset of artificial intelligence (AI) that enables machines to learn from data without being explicitly programmed. From predicting customer behavior to recognizing images and speech, it is a rapidly growing field. Adding machine learning to your toolkit can help you excel in many sectors such as finance, fraud detection, automobile, research, etc. Day 1-5: Basics of Machine Learning Before diving into its technical aspects, it is imperative to understand the fundamental concepts of machine learning. Learn about the types of machine learning, such as supervised, unsupervised, and reinforcement learning. Focus on key points, ... Read More
The Hashtable class is a part of the Java Collection Framework that stores its element in key-value pairs in a hash table. The Key is an object that can be used to fetch and receive value associated with it. There exist a few similarities between a Hashtable and HashMapclass but Hash table is synchronized. Also, its keys must be associated with values, they could not be null. This article aims to explain how Hash table works internally in Java. Working of Hashtable in Java We can consider a Hashtable as an array of buckets, where each bucket contains a list ... Read More
The backspace terminal control character is a special character represented by the ‘\b’notation. It is used to move the cursor one character back. It comes under Java escape characters, these characters are used with backslash (\) and hold a special meaning to the compiler. In this article, we will understand and see the practical implementation of‘\b’ notation through Java example programs. Working of Backspace Terminal Control Character Two types of situations may arise while working with this escape character. First, when we hard code the backspace character into a String and the second, when we take input using a keyboard. ... Read More
Java provides different ways to copy files including the ‘File’, ‘FileInputStream’ and‘FileOutputStream’ classes. There are times when we need to take a backup, compress a file or share it with others. In these situations, copying that file becomes necessary. Weare going to explore the methods and classes that will help us to copy the content of one file to another file through Java programs. Before jumping to the example program directly, let’s discuss some classes and built-in methods that we will be using. This will build a foundation for understanding the code. Note that these classes and methods are associated ... Read More
Java provides different method calls techniques that we can use according to the need andscenario in our program. Here, methods mean a block of code that can be reused multipletimes to perform a single operation. It saves our time and also reduces the size of code.The method call is referred to as invocation of methods. To use the functionality of amethod, it must be invoked by some means. This article aims to explain how methods arecalled in Java User-defined Method in Java Before discussing the method call, let’s familiarize ourselves with syntax of the userdefined methods Syntax accessSpecifier nonAccessModifier return_Type ...

The most frequent query asked by beginner programmers is that how are parameters passed in Java. Generally, the programming languages use pass by value and pass byreference for passing parameters to a method. However, Java does not support both approaches rather it uses pass by value to pass both primitive and reference type values. In this article, we are going to understand passing parameters by value through exampleprograms. Passing Parameters to a Method in Java Let’s start this discussion by understanding the storage mechanism of Java. The referencevariables, names of methods and classes are stored in stack and their values ... Read More
To encapsulate or represent a primitive datatype within an object, Java provides theconcept of Wrapper classes. All eight wrapper classes are as follows Double, Float, Long, Integer, Short, Byte, Character, and Boolean. These classes have a variety of in-builtmethods that allows us to integrate primitives into their respective instances as well asdisintegrate instances into their respective primitive datatypes. This article aims to explainthe different ways to create instances of Wrapper Classes. Creating Instances of Wrapper Classes The following approaches are available in Java to create Instances of Wrapper Classes − With the help of Constructor Although we can create an ... Read More
