It is strongly and statically typed. Compile time normally translates a program into a machine-independent bytecode representation. That bytecode is the instruction set and binary format in the Java Virtual Machine Specification, Java SE 27 Edition. Java includes automatic storage management, typically using a garbage collector. A class has a single superclass."},{"question":"What is TypeScript?","answer":"TypeScript is JavaScript with syntax for types. It is a strongly typed language that builds on JavaScript, and it is a typed superset of JavaScript, so JavaScript syntax is legal TypeScript. TypeScript is a static type checker. It preserves JavaScript runtime behavior and does not change it. After checking, it erases the types and emits JavaScript. It does not add a TypeScript runtime library. TypeScript 7.0 is available. The compiler is under the Apache License 2.0."},{"question":"Where does each language run?","answer":"A Java program is normally compiled to bytecode for a Java Virtual Machine. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: in a browser, on Node.js, Deno, Bun, and in apps. The two do not share a runtime."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/java-vs-typescript","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/java-vs-typescript), Java is a class-based, object-oriented language that compiles to Java Virtual Machine bytecode.
