Which software company announced the Java programming language in 1995?

Sun Microsystems announced the Java programming language in 1995.

Sun Microsystems publicly announced Java in May 1995. The language had been developed at Sun by a team led by James Gosling and was originally called Oak before being renamed Java.

Java was designed around the idea that programs could run on different systems through a Java Virtual Machine. This concept was summarized by the phrase “write once, run anywhere,” although real-world compatibility still depended on the environment and implementation.

Oracle later acquired Sun Microsystems in 2010, so Oracle now owns key Java assets and continues stewardship of the platform. That later ownership can cause confusion about the answer: the company that announced Java was Sun Microsystems, not Oracle.
