正如你所看到的。皮特稍稍偏左。但我希望所有的顶部线条都能很好地相互对齐。我玩过tab功能，但它只是将所有第一行进一步向右移动。
任何人都知道我如何让Piet稍微向右移动，与其他顶部线条很好地对齐。
void printStudentName(Scanner studentNameScanner) {
String studentName = scannerToStringLine(studentNameScanner);
out.printf("%s has an average grade of: ", studentName);
}
void identifyStudentName(Scanner studentNameScanner) {
studentNameScanner.useDelimiter(" ");
while(studentNameScanner.hasNext()) {
printStudentName(studentNameScanner);
}
void averageGradeOfStudent(Scanner inputScanner) {
inputScanner.useDelimiter("_");
identifyStudentName(stringToScanner(scannerToStringNext(inputScanner)));
calculateAverageGrade(stringToScanner(scannerToStringNext(inputScanner)));
}
void calculateAverageGrade(Scanner inputScanner) {
ArrayList<Integer> gradeArrayList = new ArrayList<>(); //Store grades in an array list.
inputScanner.useDelimiter(" ");
while(inputScanner.hasNext()) {
gradeArrayList.add(inputScanner.nextInt());
}
mathScoreCount = gradeArrayList.size();
determineFinalGrade(gradeArrayList, mathScoreCount);
}
void determineFinalGrade(ArrayList<Integer> gradeArrayList, int mathScoreCount) {
cumulativeMathScore = 0;
for(int i = 0; i < gradeArrayList.size(); i++) { //Access each grade in the grade array list by looping through each element of the array list.
cumulativeMathScore += gradeArrayList.get(i);
}
double mathScoreAverage = cumulativeMathScore / mathScoreCount;
printGradeAverage(mathScoreAverage);
}
void printGradeAverage(double mathScoreAverage) {
if(mathScoreAverage >= 5.5 && mathScoreAverage < 6) {
out.printf("6-n ");
} else {
out.printf("%.1fn ", Math.round(mathScoreAverage*2)*0.5);
}
}
似乎应该在打印带有学生姓名的第一行之前输出一个选项卡。
然后，一切都会很顺利。
out.printf("t")
while(studentNameScanner.hasNext()) {
printStudentName(studentNameScanner);
