James Gosling, the creator of Java computer language, confirmed on Monday that he had joined Web search giant Google Inc.

The programmer founded Java at Sun Microsystems, which was acquired by software supplier Oracle last year. Mr. Gosling showed disapproval for the sale of the company to Oracle. He left the company just a few months after the acquisition.

He complained that the new employer slashed his salary and micromanaged his work. He criticized Oracle’s Chief Executive Larry Ellison saying he was the prince of darkness.

Mr. Gosling announced his new appointment yesterday on his blog. However, he did not mention what exactly he would do at Google. In his blog, he wrote, "I don't know what I'll be working on. I expect it'll be a bit of everything, seasoned with a large dose of grumpy curmudgeon.”

Currently, Oracle is at loggers head with Google. Last summer, Oracle filed a lawsuit against Google, claiming its Android software breaches patents for the Java platform, which Oracle acquired since it purchased Sun Microsystems in a deal worth $7.2 billion.
