用户输入他们每天在同一行上工作的小时数，这样就可以计算出工作小时数，但我甚至不确定这是否可行。这是我当前代码的片段：
Sun Mon Tue Wed Thur Fri Sat
4 3 8 5 4 4 8
我目前的输出：
System.out.println("\t"+"\t"+"\t"+"\t"+"\t" + "Sun" + "\t" + "Mon" + "\t" + "Tue" + "\t" + "Wed" + "\t" + "Thur" + "\t" + "Fri" + "\t" + "Sat");
for (int j = 0; j < hoursWorkedPerDay.length; j++) {
System.out.print("Enter hours worked for Employee " + (j+1) + ":"+ "\t" + " " + " ");
for (int k = 0; k < hoursWorkedPerDay[0].length; k++) {
hoursWorkedPerDay[j][k] = scan.nextInt();
}
} // End of for loop
我的问题是，这是可能的还是我必须垂直打印？谢谢！
答案 0 :(得分：1)
您必须在获取值之前打印工作日。像这样：
cabal install gd答案 1 :(得分：1)
如果我理解你的问题，那么我如何在一行上打印一组数字＆＃39;？如果是这样，主要有两种方式：
对每个号码使用print（之间带有制表符），然后使用println结束该行。
将所有数字加入一个字符串，然后使用println输出整个字符串。
这是一个简单的Java 8习惯用法，它通过将它们连接到带有制表符分隔符的字符串，在单个语句中打印所有小时：
IntStream.range(0, employeeCount)
.mapToObj(emp -> Arrays.stream(hoursWorked[emp]).collect(Collectors.joining("\t")))
.forEach(System.out::println);
