Answer:

a. facilitate improvements but do not necessarily cause them.

Explanation:

Decision Support Systems are interactive Information systems that assist  decision makers in coming up with strategies that help the organisation achieve its goals .The model base of the DSS uses mathematical and statistical models to analyse information then it generates reports and suggest possible solutions that can be implemented .The system is capable of giving a specific solution and some even allow the decision makers to give input before suggesting the most applicable solution.The effectiveness of a DSS is equally as important as its efficiency .The DSS unlike the conventional decision-making process should be able to analyse information effectively and come up with solutions in the shortest possible time frame.

Roman55 [17]

Answer:

Option a, b, d, f, and j is legal method calls.

Explanation:

In the given question some information is missing, that is the method definition which can be described as follows:

Method definition:

int x =2, y=3; //defining integer variable

int mathMethod (int x)  //method definition

int z=x+y; //calculate value

return z;  //return value

}

In the given question option a, b, d, f, and j  is legal, because these options follow the correct syntax, and other option were incorrect which can be defined as follows:

  • In option c, It is illegal because it accepts only one parameter.
  • In option e, It is accepts long number, that's why it is illegal.
  • In option g, It accepts float value, that's why it is illegal.
  • In option h, It doesn't accepts any parameter.
  • In option i, It isn't use in method.

Suppose you are provided with 2 strings to your program. Your task is to join the strings together so you get a single string wi
Mariulka [41]

Answer:

public class TestImport{

   public static void main(String[] args) {

       String string1 = args[1];

       String string2 = args[2];

       System.out.println(string1 +" " +string2);

   }

}

Explanation:

The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);

When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.
