The directions are:
方向是:
"For your output use a loop to print the student names, percentages, and test score, and be sure to include appropriate data below each column heading:
“对于您的输出,使用循环打印学生姓名,百分比和测试分数,并确保在每个列标题下方包含适当的数据:
Student Name Student Percentage Student Test Score."
学生姓名学生百分比学生考试成绩。“
I'm not sure how to do this!
我不知道怎么做!

How about:
for(i=0; i<scores.length; i++)
System.out.println(last_names[i] +"\t"+ final_percent[i] +"\t"+ scores[i]);
-
A
for
loop is used because you want to loop through the entire array of a known size.使用for循环是因为您想循环遍历已知大小的整个数组。
If, instead, you wanted to loop only while a certain condition holds you would use a
while
loop: (e.g.while(condition) loop;
).相反,如果您只想在某个条件成立时循环,则使用while循环:(例如while(condition)loop;)。
-
System.out.println()
will print a new line after each call, and\t
will add a tab.
System.out.println()将在每次调用后打印一个新行,并且\ t将添加一个选项卡。
