How to make this pattern only used 3for?

Question

n = 3

1
2 3 4
5 6 7 8 9
8 7 6
5

Answer 1

int line=3,count=0,limit=1,inc=1,sp=3,splimit=-2;
for(int i=0;i<2*line;++i)
{
for(sp=0;sp<abs(splimit);++sp)
cout<<" ";
++splimit;
for(int j=1;j<2*limit;++j)
{
count=count+inc;
cout<<count;
}
cout<<endl;
if(i<line-1)
{++limit;inc=1;}
else
{--limit;inc=-1;}
}

This is a not so good c++ implementation but it does work and has three for loops. Hope someone sees it and helps out me with it in java.

EDIT: removed few unnecessary variables
int line=3,count=1;
for(int i=0;i<2*line-1;++i)
{
for(int sp=0;sp<abs(line-1-(abs(line-1-abs(line-1-i))));++sp)
cout<<" ";
for(int j=0;j<2*(abs(line-1-abs(line-1-i)))+1;++j)
{
cout<<count;
(i<line)?count++:count--;
}
cout<<endl;
if(i==line-1) count-=2;
}
