java.util.Arrays Class

The Arrays class provides static methods to manipulate arrays. Table 6.1 shows some of its methods.

Method	Description
asList	Returns a fixed-size List backed by the array. No other elements can be added to the List. List is discussed in Chapter 14, “The Collection Framework.”

equals	Compares the contents of two arrays.
fill	Assigns the specified value to each element of the specified array.
