Create 8 ants...Created 8 ants. They are:
ID = 0, x=0, y=0, weight = 0.00
ID = 1, x=1, y=2, weight = 4.20
ID = 2, x=2, y=4, weight = 8.40
ID = 3, x=3, y=6, weight = 12.60
ID = 4, x=4, y=8, weight = 16.80
ID = 5, x=5, y=10, weight = 21.00
ID = 6, x=6, y=12, weight = 25.20
ID = 7, x=7, y=14, weight = 29.40

Again the Ants are:
ID = 0, x=0, y=0, weight = 0.00
ID = 1, x=1, y=2, weight = 4.20
ID = 2, x=2, y=4, weight = 8.40
ID = 3, x=3, y=6, weight = 12.60
ID = 4, x=4, y=8, weight = 16.80
ID = 5, x=5, y=10, weight = 21.00
ID = 6, x=6, y=12, weight = 25.20
ID = 7, x=7, y=14, weight = 29.40

Send doSomething() to the Ants, print return value:
Ant ID=0 (wt=0.00) sent doSomething():
   - Ant ID=0 sent getUniformRandomFractionOf( 0.000 ):   -> r = 0.25233
   --> returnValue=0.000 -->  -- returned 0.0 to variable d in Main.
Ant ID=1 (wt=4.20) sent doSomething():
   - Ant ID=1 sent getUniformRandomFractionOf( 4.200 ):   -> r = 0.44585
   --> returnValue=1.873 -->  -- returned 1.9 to variable d in Main.
Ant ID=2 (wt=8.40) sent doSomething():
   - Ant ID=2 sent getUniformRandomFractionOf( 8.400 ):   -> r = 0.92860
   --> returnValue=7.800 -->  -- returned 7.8 to variable d in Main.
Ant ID=3 (wt=12.60) sent doSomething():
   - Ant ID=3 sent getUniformRandomFractionOf( 12.600 ):   -> r = 0.78685
   --> returnValue=9.914 -->  -- returned 9.9 to variable d in Main.
Ant ID=4 (wt=16.80) sent doSomething():
   --> returnValue=1.040 -->  -- returned 1.0 to variable d in Main.
Ant ID=5 (wt=21.00) sent doSomething():
   - Ant ID=5 sent getUniformRandomFractionOf( 21.000 ):   -> r = 0.14537
   --> returnValue=3.053 -->  -- returned 3.1 to variable d in Main.
Ant ID=6 (wt=25.20) sent doSomething():
   --> returnValue=1.560 -->  -- returned 1.6 to variable d in Main.
Ant ID=7 (wt=29.40) sent doSomething():
   - Ant ID=7 sent getUniformRandomFractionOf( 29.400 ):   -> r = 0.69948
   --> returnValue=20.565 -->  -- returned 20.6 to variable d in Main.

Removed Ant from position (index) 3:
ID = 3, x=3, y=6, weight = 12.60
The list now:
 ID = 0, weight = 0.000
 ID = 1, weight = 4.200
 ID = 2, weight = 8.400
 ID = 4, weight = 16.800
 ID = 5, weight = 21.000
 ID = 6, weight = 25.200
 ID = 7, weight = 29.400

List after add Ant (wt=1000) back to pos=3:
 ID = 0, weight = 0.000
 ID = 1, weight = 4.200
 ID = 2, weight = 8.400
 ID = 3, weight = 1000.000
 ID = 4, weight = 16.800
 ID = 5, weight = 21.000
 ID = 6, weight = 25.200
 ID = 7, weight = 29.400

The list after adding ant again to end:
 ID = 0, weight = 0.000
 ID = 1, weight = 4.200
 ID = 2, weight = 8.400
 ID = 3, weight = 1000.000

 ID = 5, weight = 21.000
 ID = 6, weight = 25.200
 ID = 7, weight = 29.400
 ID = 3, weight = 1000.000

The list after setting weight of anAnt to 20000:
 ID = 0, weight = 0.000
 ID = 1, weight = 4.200
 ID = 2, weight = 8.400
 ID = 3, weight = 20000.000
 ID = 4, weight = 16.800
 ID = 5, weight = 21.000
 ID = 6, weight = 25.200
 ID = 7, weight = 29.400
 ID = 3, weight = 20000.000

The list after removing it by reference:
 ID = 0, weight = 0.000
 ID = 1, weight = 4.200
 ID = 2, weight = 8.400
 ID = 4, weight = 16.800

The list categorized:
Ant 0 wt = 0.881 (wt > 0.7).
Ant 1 wt = 0.983 (wt > 0.7).
Ant 2 wt = 0.034 (wt < 0.3).
