It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

program, which would be done with position = "Hello, World". indexOf ("World"), which would return 7. If one instead asks for the position = "Hello, World". indexOf ("Goodbye") the code will "fail", as the search term does not appear in the string.
