【问题描述】:
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.StringTokenizer;
public class Graph1 {
public static void main(String[] args) throws FileNotFoundException {
int linecount = 0, ec = 0;
int nbin = 0, cbin = 0;
int[][] data = new int[6][6];
String e = "e";
Scanner sc = new Scanner(System.in);
System.out.print("Enter input file name: ");
String newfile = sc.nextLine() + ".txt";
File file = new File(newfile);
Scanner scan = new Scanner(file);
while ((scan.hasNext())) {
StringTokenizer t = new StringTokenizer(scan.nextLine());
if(t.nextToken().equals(e)) {
ec++;System.out.print("ec.." + ec );
nbin = Integer.parseInt(t.nextToken());
cbin = Integer.parseInt(t.nextToken());
data[nbin][cbin] = 1;
}
}
输入文件是:
jjjjjjjjj
e 1 3
e 2 5
e 3 4
e 4 1
e 5 3
我想从文件条目创建邻接列表。我的代码给出了邻接矩阵。我听说java中有特定的邻接列表功能请帮助
