Both the methods do the same thing i.e, runs the garbage collector. But there are some differences:

1)System.gc() is a class method where as Runtime.gc() is an instance method.

2) System.gc() method is static so more conveninent to use in comparison to gc() method of Runtime class (Runtime.getRuntime().gc()).
