How to use this tool?

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

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

Examples

The following are examples of code conversion from Java to Fortran 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 Java and Fortran

CharacteristicJavaFortran
SyntaxJava has a C-style syntax, which is similar to C++ and C#. It uses curly braces to define blocks of code and semicolons to end statements.Fortran has a unique syntax that is different from most other programming languages. It uses keywords and statements that are specific to Fortran.
ParadigmJava is an object-oriented programming language that supports imperative, functional, and concurrent programming paradigms.Fortran is a procedural programming language that supports imperative programming paradigms.
TypingJava is a statically typed language, which means that the data type of a variable is determined at compile time.Fortran is a statically typed language, which means that the data type of a variable is determined at compile time.
PerformanceJava is known for its good performance due to its Just-In-Time (JIT) compiler, which compiles bytecode into machine code at runtime.Fortran is known for its excellent performance in scientific and engineering applications due to its efficient memory management and optimized compilers.
Libraries and frameworksJava has a vast collection of libraries and frameworks, including Spring, Hibernate, and Apache Struts, which make it easy to develop complex applications.Fortran has a limited collection of libraries and frameworks compared to Java, but it has libraries for scientific and engineering applications, such as LAPACK and BLAS.
Community and supportJava has a large and active community of developers and users, and it is supported by Oracle, which provides regular updates and bug fixes.Fortran has a smaller community compared to Java, but it is still actively used in scientific and engineering applications, and it is supported by vendors such as Intel and IBM.
Learning curveJava has a moderate learning curve, and it is relatively easy to learn for programmers who are familiar with C++ or C#.Fortran has a steep learning curve, and it is more challenging to learn compared to Java due to its unique syntax and limited resources for learning.
