In Java all the methods should include all the given options except “a call to another method”.
Hence, the correct answer is option “A”.

Explanation of Solution
Method:
A collection of statements which are formed together to perform an operation is called as method.
Declaration of a method:
Method declaration gives the description of what the method should perform; Method declaration holds the modifier, return type, name of the method, the list of parameters and the body of the method.
Syntax for defining a method:
modifier return_type methodName(list of parameters)
{
//body
}
Example:
public int findArea(int x, int y)
{
//body
}
The above statement shows the declaration of the method; here,
- public – modifiers
- int – return type
- findArea – name of the method
- x, y – formal parameters
- int x, int y – list of parameters
- Body is the part of the method that contains the statements and the operations to be performed.
Braces:
- Braces usually enclose the number of statements.
- In a function, the numbers of statements are enclosed within the braces.
- The opening of the function contains the open braces “{”.
- The ending of the function contains the close braces “}”.

Then to choose a random number from 1 to 100 and the computer program will attempt to guess it, displaying the directions calculated or not. The guess will be displayed and the user will answer if it was correct or not. If correct, the game ends, if not then the computer asks if the guess was too high or too low. Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”. The program ending when the user guesses correctly or after the program takes 6 guesses. HELP ASAP!arrow_forward
