main.java

一个用java实现的词法和语法分析器

package jywhu;

public class Main {
	public static void main(String[] args){
		if(args.length==0){
			System.err.println("请指定源文件");
		}else{
			AccAnalyse acc=new AccAnalyse(args[0]);
			acc.analyse();
			Token token=acc.getToken();
			GrammarAnalyse grammar=new GrammarAnalyse(acc,token);
			grammar.printTree(grammar.stmtSequence());
			//System.out.println(grammar.stmtSequence().toString());
			}
	}
}
