Example 14.16-1. The continue Statement
In the Graph class in § 14.15 , one of the break statements is used to finish execution of
the entire body of the outermost for loop. This break can be replaced by a continue if
the for loop itself is labeled:

class Graph {
int edges[][];
public Graph(int[][] edges) { this.edges = edges; }
public Graph loseEdges(int i, int j) {
int n = edges.length;
int[][] newedges = new int[n][];
edgelists:
for (int k = 0; k < n; ++k) {
int z;
search:
{
if (k == i) {
for (z = 0; z < edges[k].length; ++z) {
if (edges[k][z] == j) break search;
}
} else if (k == j) {
for (z = 0; z < edges[k].length; ++z) {
if (edges[k][z] == i) break search;
}
}
// No edge to be deleted; share this list.
newedges[k] = edges[k];
continue edgelists;
} //search
// Copy the list, omitting the edge at position z.
int m = edges[k].length - 1;
int ne[] = new int[m];
System.arraycopy(edges[k], 0, ne, 0, z);
System.arraycopy(edges[k], z+1, ne, z, m-z);
newedges[k] = ne;
} //edgelists
return new Graph(newedges);
}
}
Which to use, if either, is largely a matter of programming style.
