All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`int`	`distance(Pos p)` Returns the "manhatttan distance" between "this" position and p.
`boolean`	`equals(java.lang.Object o)` Tests for equaltiy of a Pos with an arbitraty object.
`boolean`	`equals(Pos p)` Tests for equality of row/col coordinates between two positions.
`int`	`getCol()` returns the column for this position.
`int`	`getRow()` returns the row for this position.
`int`	`hashCode()` Returns a hashcode for Pos objects that is OK for our Project3 application.
`static Pos`	`read(java.util.Scanner sc)` Reads a new position from scanner sc, e.g.
`Pos`	`sum(Pos p)` Returns a new point whose row is the sum of this's row and p's row, and column likewise.
`java.lang.String`	`toString()` Returns a string representation, e.g.

- Constructor Detail
  - Pos
```
public Pos(int r,
           int c)
```
    Constructs a position from row r and column c.
  - Pos
```
public Pos(Pos p)
```
    Constructs a position from Pos p
- Method Detail
  - getRow
```
public int getRow()
```
    returns the row for this position.
  - getCol
```
public int getCol()
```
    returns the column for this position.
  - toString
```
public java.lang.String toString()
```
    Returns a string representation, e.g. "12 28".
    
    Overrides:
    
    toString in class java.lang.Object
  - equals
```
public boolean equals(Pos p)
```
    Tests for equality of row/col coordinates between two positions.
  - equals
```
public boolean equals(java.lang.Object o)
```
    Tests for equaltiy of a Pos with an arbitraty object. This is important for use in some collections.
    
    Overrides:
    
    equals in class java.lang.Object
  - distance
```
public int distance(Pos p)
```
    Returns the "manhatttan distance" between "this" position and p. This distance is the sum of the absolute values of the differences in row coordinates and column cooridinates.
  - sum
```
public Pos sum(Pos p)
```
    Returns a new point whose row is the sum of this's row and p's row, and column likewise. E.g.g (row=2,col=7) + (row=10,col=4) gives (row=12,col=11).
  - read
```
public static Pos read(java.util.Scanner sc)
```
    Reads a new position from scanner sc, e.g. "12 17" would produce (row=12,col=17).
  - hashCode
```
public int hashCode()
```
    Returns a hashcode for Pos objects that is OK for our Project3 application. This allows for HashMap's and HashSet's of Pos objects.
    
    Overrides:
    
    hashCode in class java.lang.Object
