三角形问题

[skyboy0720]

public class Testf
{
public static void main ( String [ ] args )
{
int max = 10, l1, l2, l3;
for ( int i = 1; i <= max; i ++ )
{
for ( int j = 1; j <= max; j ++ )
{
for ( int k = 1; k <= max; k ++ )
{
l1 = ( int ) Math.pow ( i, 2 );
l2 = ( int ) Math.pow ( j, 2 );
l3 = ( int ) Math.pow ( k, 2 );
System.out.print ( "l1+l2= " + ( l1 + l2 ) + "l3= " + l3 );
if ( 13 == ( l2 + l1 ) )
{
System.out.println ( "l1= " + i + " " + "l2= " + j + " " + "l3= " + k );
}
}
}
}
}
}


这是我写的一个关于勾股定理的问题，为什么运行结果却不正确，算法错在哪呢？！

int max = 10, l1, l2, l3;
没有明确赋值啊

if ( 13 == ( l2 + l1 ) )
好像写的是 十三 不是 L3

public class Testf
{
public static void main ( String [ ] args )
{
int max = 10, l1, l2, l3 ,t;
for ( int i = 1; i <= max; i ++ )
{
for ( int j = 1; j <= max; j ++ )
{
for ( int k = 1; k <= max; k ++ )
{
l1 = ( int ) Math.pow ( i, 2 );
l2 = ( int ) Math.pow ( j, 2 );
l3 = ( int ) Math.pow ( k, 2 );


if ( l3 == ( l2 + l1 ) )
{ System.out.println ( "l1+l2=" + ( l1 + l2 ) + " " + "l3= " + l3 );
System.out.println ( "l1= " + i + " " + "l2= " + j + " " + "l3= " + k );
}
}
}
}
}
}

这样就可以了，System.out.print ( "l1+l2= " + ( l1 + l2 ) + "l3= " + l3 );写在外面，那不是每次都要循环了吗？还有把if ( l3 == ( l2 + l1 ) )中l3 写成13，

哈哈，我想起来了，运行结果全是L1=3，L2=2，然后L3是1到10。

真的是写成13了，我显示器焦距不好了，很不清楚，晕啊！！谢谢提醒
