equals. This method indicates the MWArray obje ct is equal to the input

object. The

equals method of the MWArray classoverridestheequals method

of class

Object.

The prototype for the

equals m ethod is as follows:

public boolean equals(Object object)

Input Parameters

object

Array to compare this MWArray object to

Example — Comparing MWArrays with equals

Create a shared copy of the MWArray object and then compare it to the original

object. A return value of

true indicates that the two o bjects are equal:

Object S = A.sharedCopy();

if (A.equals(S))

System.out.println("Matrix S is equal to matrix A");

When run, the example displays this output:

Matrix S is equal to matrix A

hashCode. This method returns a hash code value for the MWArray object.

The

hashCode method of the MWArray class overrides the hashCode method

of class

Object.

The prototype for the

hashCode method is as follows:

public int hashCode()

Input Parameters
