Answer:
The answer to this question can be given as:
Method Definition:
void printGrade(char x) //declare method with parameter.
{
//method body
System.out.println("Grade: "+x);
//print value in new line.
}
Explanation:
In the above method definition, we define a method that's name is already given in the question that is printGrade. This method does not return any value because its return type is void. In this method, we pass a char variable as a parameter. Then we define the method body in the method body we print the value of the char variable in the new line. To print the value in the new line we use the println function in java.
