关于数据结构的JAVA源代码

public class StringCompare{
	public static int compare(String s,String t){
		int n=s.length();
		int m=t.length();
		int i=0,j=0,tag;
		while(i<n&&j<m){

				tag=-1;
				return tag;
			}
		}
		if(n==m) tag=0;
		else if(n>m) tag=1;
		else tag=-1;
		return tag;
	}
	
	public static void main(String[] args){
