Compilers turn Java into bytecode that any machine with a Java virtual machine can execute unchanged Sun Microsystems released Java in 1995, aiming first at set top boxes and then at web applets, with bytecode as a portable middle form. A virtual machine interprets that bytecode or compiles it on the fly for the host processor. The portability cost some speed, but the model later carried over to Android and to large server systems. It sits in Mondo's technology collection, one of 200 facts that each trace back to the reference below.
