Write a switch statement to convert a letter grade into an equivalent numeric value on a four-point scale. Set the value of the variable gradeValue to 4.0 for an A, 3.0 for a B, 2.0 for a C, 1.0 for a D, and 0.0 for an F. For any other letter, set the value to 0.0 and display an error message.

Question

Answer 1

```
switch(letter){
case 'A':
gradeValue = 4.0;
break;
case 'B':
gradeValue = 3.0;
break;
case 'C':
gradeValue = 2.0;
break;
case 'D':
gradeValue = 1.0;
break;
case 'F':
gradeValue = 0.0;
break;
default:
gradeValue = 0.0;
System.out.println("The grade "
+ letter + " is not valid");
}
```
