Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is : 4.
When you run this program in Java. The output produce by this program is 4
The given code is:
import java.util.ArrayList;
public class arrayList7
{
public static void main(String[] args) {
ArrayList one = new ArrayList ();
Integer count=3;
count=count+1;
one.add(2);
one.add(count);
System.out.println(one.get(1));
}
}
This code store the value in ArrayList one variable. It first adds 2 at zero indexes and 4 at first index. When you print the value at index one, you will get the output 4. because the count variable contains 4. If you want to print 2, then you specify the print statement that prints the value at index zero. eg.
System.out.println(one.get(0));
Answer:
Explanation:
The following code is written in Python and creates a tuple of 5 integer numbers and then prints out the tuple. Tuples are immutable objects meaning that they cannot be changed at all. Therefore, they have no append methods and cannot have any values added or removed so the last two tasks of this question are impossible to accomplish.
my_tuple = (2, 5, 7, 9, 6)
print(my_tuple)
Answer:
A pneumatic system is a system that uses compressed air to transmit and control energy. Pneumatic systems are used extensively in various industries. Most pneumatic systems rely on a constant supply of compressed air to make them work. This is provided by an air compressor.
A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. The fluid is theoretically uncompressible and the fluid path can be flexible in the same way as an electric cable.
Explanation:
<h3>Examples of pneumatic systems and components
</h3><h3>Air brakes on buses and trucks.
</h3><h3>Air brakes on trains.
</h3><h3>Air compressors.
</h3><h3>Air engines for pneumatically powered vehicles.
</h3><h3>Barostat systems used in Neurogastroenterology and for researching electricity.
</h3><h3>Cable jetting, a way to install cables in ducts.
</h3><h3>Dental drill.</h3>
<h3>Hydraulic systems use the pump to push hydraulic fluid through the system to create fluid power. The fluid passes through the valves and flows to the cylinder where the hydraulic energy converts back into mechanical energy. The valves help to direct the flow of the liquid and relieve pressure when needed.</h3>
