In Java, arrays are a fundamental data structure used to store a fixed-size sequential collection of elements of the same type. arraycopy should give you the closest you can get to native performance. Performance of System. They have a fixed size that‘s defined when instantiated. In this In this tutorial, you will learn about different ways you can use to copy arrays (both one dimensional and two-dimensional) in Java with the help of examples. System. I've The arraycopy () method can be used to copy quickly an array of any type from one place to another. arraycopy () System.
