Which is better for data science Python or Java?

Java vs Python for Data Science- Performance In terms of speed, Java is faster than Python. It takes less time to execute a source code than Python does. Python is an interpreted language, which means that the code is read line by line. This generally results in slower performance in terms of speed.

Can Java be used for data analysis?

Java is usable in a number of processes in the field of data science and throughout data analysis, including cleaning data, data import and export, statistical analysis, deep learning, Natural Language Processing (NLP), and data visualization.

Do Data Analyst use Java?

For data scientists, Java provides a host of data science functionalities such as data analysis, data processing, statistical analysis, data visualization, and NLP. Java can help apply machine learning algorithms to real-world applications.

What is data cleansing in Python?
