Chris

Bob : 1234

sue : 5678

Chris : 2468

Explanation:

In this code, when we create the class object, that is "stu1, stu2, and stu3" and call the parameterized constructor bypassing the "string and integer" value and print the object value you forget to call the "tostring" method because it is the only method which returns both "string and integer" value.

A. CAD

Explanation:

Computer Aided Design, CAD, is basically for design. It involves the use of a computer to assist in the process of designing a part, circuit, building, etc.

It is also for drafting, here it makes use of a computer to assist in the process of communicating a technical drawing.

CAD has a couple of models in which its drawings and designs are represented. namey;

Solid Modeling: This is a type of 3D CAD process in which volumes of an object are represented not just its lines and surfaces.

Wireframe Modeling: This is a 3D CAD process that represents the lines and surfaces of a design.

Additive Modeling: This is a 3D modelling method in which each component is created individually and subsequent components are created as needed. This method is represented by construction processes such as welding, gluing, mechanical fastening, joinery.

Subtractive Modeling: This is a 3D modelling method in which a design is created by removing different geometric shapes from a solid block larger than the final design. The method is can best be represented by milling, drilling, turning, grinding, and other manufacturing processes.

Susie can make use of CAD and pitch its importance to his clients.

svp [43]

Answer:

public static String repeat(String text, int repeatCount) {

if(repeatCount < 0) {

throw new IllegalArgumentException("repeat count should be either 0 or a positive value");

}

if(repeatCount == 0) {

return "";

} else {

return text + repeat(text, repeatCount-1);

}

Explanation:

Here repeatCount is an int value.

at first we will check if repeatCount is non negative number and if it is code will throw exception.

If the value is 0 then we will return ""

If the value is >0 then recursive function is called again untill the repeatCount value is 0.
