Question

我是java的新手，我编写了代码来显示以下并行数组的值：

short[] Years = {1995, 1997, 1998,1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012};

String[] Months = {"January", "February", "June", "January", "March", "June", "July", "August", "September", "March", "May", "January", "March", "July", "November", "March", "June"};

目前，当我运行它时，它们彼此显示在一起。我试图让它并排展示。我怎么能这样做？

这是显示它们的代码：

System.out.println("Years");
for(short temp: years)
{
System.out.println(temp);
}
System.out.println("Months");
for(String temp: months)
{
System.out.println(temp);
}

Answer 1

试试这个：

int length = Years.length > Months.length ? Months.length : Years.length;
for(int index = 0; index < length; index++) {
    System.out.println(Years[index] + '\t' + Months[index]);
}

我建议阅读this

Answer 2

如果长度相等：

for (int i = 0; i < Years.length; i++) {
    System.out.println(Years[i] + '\t' + Months[i]);
}

Answer 3

你可以这样做：

 short[] years = {1995, 1997, 1998,1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012};
    String[] winners = {"January", "February", "June", "January", "March", "June", "July", "August", "September", "March", "May", "January", "March", "July", "November", "March", "June"};
    System.out.println("Years"+"\t"+"Premiers");
    int i = years.length-1;
    int j= winners.length-1;
    int  k=0;
int l=0;
    do{
            i--;
            j--
        System.out.println(years[k++]+"\t"+winners[l++]);
    }while(i>=0 || j>=0);

您将找到如下输出：

Years   Premiers
1995    January
1997    February
1998    June
1999    January
2000    March
2001    June
2002    July
2003    August
2004    September
2005    March
2006    May
2007    January
2008    March
2009    July
2010    November
2011    March
2012    June
