How to use this tool?

This free online converter lets you convert code from Fortran to Java in a click of a button. To use this converter, take the following steps -

  1. Type or paste your Fortran code in the input box.
  2. Click the convert button.
  3. The resulting Java code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from Fortran to Java using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Example 1 - Is String Palindrome

Program that checks if a string is a palindrome or not.

Key differences between Fortran and Java

CharacteristicFortranJava
SyntaxFortran uses a fixed-format syntax, which can be difficult to read and write for some programmers. However, it has a simple and concise syntax that makes it easy to learn and use.Java uses a C-style syntax, which is familiar to many programmers. It has a more verbose syntax than Fortran, but it is also more flexible and expressive.
ParadigmFortran is primarily a procedural language, but it also supports some object-oriented programming features. It is often used for scientific and engineering applications.Java is an object-oriented language that supports imperative, functional, and procedural programming paradigms. It is widely used for web and mobile development, as well as enterprise applications.
TypingFortran is a statically typed language, which means that variable types are determined at compile time. It has limited support for dynamic typing.Java is also a statically typed language, but it has more advanced support for dynamic typing through the use of generics and reflection.
PerformanceFortran is known for its high performance and efficiency, especially for scientific and engineering applications that require complex mathematical calculations.Java is generally slower than Fortran, but it has improved significantly in recent years and is now suitable for many high-performance applications.
Libraries and frameworksFortran has a limited number of libraries and frameworks compared to Java, but it has a strong ecosystem for scientific and engineering applications.Java has a vast array of libraries and frameworks for almost any application domain, including web development, mobile development, and enterprise applications.
Community and supportFortran has a smaller community than Java, but it is still active and has a strong presence in scientific and engineering communities.Java has a large and active community with many resources and support options available, including online forums, documentation, and training courses.
Learning curveFortran has a steeper learning curve than Java, especially for programmers who are not familiar with scientific and engineering applications. However, it is still relatively easy to learn compared to other low-level languages.Java has a relatively low learning curve, especially for programmers who are already familiar with C-style syntax. It has a large number of resources and tutorials available to help new programmers get started.
