LandTract.java

/**
 * Make a LandTract class with the following fields:
 * 
 * • length - an int containing the tract's length • width - an int containing
 * the tract's width
 * 
 * The class should also have the following methods:
 * 
 * area - returns an int representing the tract's area equals - takes another
 * LandTract object as a parameter and returns a boolean saying whether or not
 * the two tracts have the same dimensions (This applies regardless of whether
 * the dimensions match up. i.e., if the length of the first is the same as the
 * width of the other and vice versa, that counts as having equal dimensions.)
 * toString - returns a String with details about the LandTract object in the
 * format: LandTract object with length 30 and width 40 (If, for example, the
 * LandTract object had a length of 30 and a width of 40.) Write a separate
 * program that asks the user to enter the dimensions for the
 * 
 * two tracts of land (in the order length of the first, width of the first,
 * length of the second, width of the second). The program should print the
 * output of two tracts' toString methods followed by a sentence stating whether
 * or not the tracts have equal dimensions. (If the tracts have the same
 * dimensions, print, "The two tracts have the same size." Otherwise, print,
 * "The two tracts do not have the same size.") Print all three statements on
 * separate lines.
