<p><em><em>其实通过比较我们就可以很容易看到，这个 程序JAVA和C的代码都是差不多的。只是细节上有一些变化。有个不同就是我不不知道JAVA里面有没有类似</em>**<em>printf (“%d</em>%d=%-4d”,i,j,s);这样的语句。即实现左对齐。</em>*于是我在JAVA里面想到了这样一个办法。再输出一行，让它打印空格就好。</p>
|
||
<p> ** System.out.print(a+”*”+b+”=”+s);</p>
|
||
<p> System.out.print(“ ”);**</p>
|
||
<p><strong>当然我也试过这样一种方法。即System.out.print(a+”*”+b+”=”+s “ ”)但是通过编译发现这样是行不通的。</strong></p>
|
||
<p><strong>还有一个就是我晓得了那个String ()agrs .它其实就是一个数组其实相当于是程序比不可少的东西，不管怎样你都要写出来，但是你还是可以选择不在程序里面使用它。</strong><br>.</p>
