if 문 두번째

int point = 91;
if (point >= 90) {
System.out.println("A학점");
}
if (point >= 80 && point < 90) {
System.out.println("B학점");
}
if (point >= 70 && point < 80) {
System.out.println("C학점");
}
if (point >= 60 && point < 70) {
System.out.println("D학점");
}
if (point < 60) {
System.out.println("F학점");
}
결과값 : A 학점
