if statements in java

[Joanna Spence]

I am traversing an adjacency matrix

if I am in a for loop and want to check if
an adj matrix adjmatrix[x][y] has an entry at index x and index y in a if statement; how would i do that?

right now i have

[code]
if(adj[x][y] && value[x]< -priority)
{
}

but java doesn't like it

So, how would I say, in an "if" statement

if the adjacency matrix has an entry at [x][y]
how would i write that in java?

Thanks.
