Question

java program:give one grade such as 76 the program should print out the result " your grade is C"
楼上的很多条件都多余了……比如
if (score >= 80 && score < 90) {
System.out.println("your grade is B");
}
既然能走到这里score肯定是小于90的,所以应该是这样才对……
public void static main(String[] args) {
int score=90;
if (score >= 90) {
System.out.println("your grade is A");
} else if (score >= 80) {
System.out.println("your grade is B");
} else if (score >= 70) {
System.out.println("your grade is C");
} else if (score >= 60 ) {
System.out.println("your grade is D");
} else if (score < 60) {
System.out.println("your grade is E ,you failed");
}
}
so like you said if the condition all satisfied by above then the last conditon should be
else {
System.out.println("your grade is E,you failed.")
}
because the above conditions have been checked?
