Method Detail

QuickSort
public static void QuickSort(java.util.Vector v) throws java.lang.ClassCastException
This is a generic version of C.A.R Hoare's Quick Sort algorithm. This will handle vectors that are already sorted, and vectors with duplicate keys. Equivalent to:QuickSort (v, 0, v.size () - 1);
- Parameters:
v
- AVector
ofOrdered
items.- Throws:
java.lang.ClassCastException
- If the vector contains objects that are notOrdered
.
-
QuickSort
public static void QuickSort(java.util.Vector v, int lo0, int hi0) throws java.lang.ClassCastException
This is a generic version of C.A.R Hoare's Quick Sort algorithm. This will handle vectors that are already sorted, and vectors with duplicate keys.If you think of a one dimensional vector as going from the lowest index on the left to the highest index on the right then the parameters to this function are lowest index or left and highest index or right.
- Parameters:
v
- AVector
ofOrdered
items.lo0
- Left boundary of vector partition.hi0
- Right boundary of vector partition.- Throws:
java.lang.ClassCastException
- If the vector contains objects that are notOrdered
.
-
QuickSort
public static void QuickSort(Ordered[] a)
This is a generic version of C.A.R Hoare's Quick Sort algorithm. This will handle arrays that are already sorted, and arrays with duplicate keys.Equivalent to:
QuickSort (a, 0, a.length - 1);
- Parameters:
a
- An array ofOrdered
items.
-
QuickSort
public static void QuickSort(Ordered[] a, int lo0, int hi0)
This is a generic version of C.A.R Hoare's Quick Sort algorithm. This will handle arrays that are already sorted, and arrays with duplicate keys.If you think of a one dimensional array as going from the lowest index on the left to the highest index on the right then the parameters to this function are lowest index or left and highest index or right.
- Parameters:
a
- An array ofOrdered
items.lo0
- Left boundary of array partition.hi0
- Right boundary of array partition.
-
QuickSort
public static void QuickSort(java.lang.String[] a)
This is a string version of C.A.R Hoare's Quick Sort algorithm. This will handle arrays that are already sorted, and arrays with duplicate keys.Equivalent to:
QuickSort (a, 0, a.length - 1);
- Parameters:
a
- An array ofString
items.
-
QuickSort
public static void QuickSort(java.lang.String[] a, int lo0, int hi0)
This is a string version of C.A.R Hoare's Quick Sort algorithm. This will handle arrays that are already sorted, and arrays with duplicate keys.If you think of a one dimensional array as going from the lowest index on the left to the highest index on the right then the parameters to this function are lowest index or left and highest index or right.
- Parameters:
a

-
QuickSort
public static void QuickSort(Sortable sortable)
This is a generic version of C.A.R Hoare's Quick Sort algorithm. This will handle Sortable objects that are already sorted, and Sortable objects with duplicate keys.Equivalent to:
