Answer:C. Systematic Sampling
Explanation:
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.
Systematic sampling involves selecting items from an ordered population using a skip or sampling interval. The use of systematic sampling is more appropriate compared to simple random sampling when a project's budget is tight and requires simplicity in execution and understanding the results of a study.
package mypackage; // Whatever package this should be in.
public abstract class DesktopComponent {
private String type;
// Alternatively you may want a final variable.
// private final String type;
public DesktopComponent(String type)
{
this.type = type;
}
abstract void onClick();
}
