A switch statement is used for single values like 1,2 3, etc. If you want to test for a range of values (1 to 5, 6 to 10, etc), an if/else if chain would be better.

ok ty guess its something like this

if (grade > 90 && grade <= 100) {
grade= 'A';
} else if (grade > 80 && grade <= 89) {
grade= 'B';
} else if (grade > 70 && grade <= 79) {
grade= 'C';
} else if (grade > 60 && grade <= 69) {
grade= 'D';
} else if (grade> 0 && grade <= 59) {
grade= 'F';
}
System.out.print( grade);

will try
