To find minimum number in lower triangle of matrix

Example:
1 0 0
2 3 0
4 5 6


public class arraydemotriangleAmin {

static void triangleAmin(int x[][])
{
int i,j,min=0;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{min=x[0][0];

if(i<=j)
{

if(x[i][j] {
min=x[i][j];
}
}
}
}
System.out.println("The Min Value in triangle A is:"+ min);
}
public static void main(String[] args)
{
triangleAmin(new int[][]{{1,2,3},{4,5,6},{7,8,9}});
}

}
