java正则过滤汉字

利用正则过滤汉字

package lin;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class SubFile {

	

	public static void main(String[] args){
		
			String  str = "银行业存款类金融机构协助查冻扣账户数量[3041900001#01]<=银行业存款类金融机构协助查询账户数量[3041900001#b1]+银行业存款类金融机构协助冻结账户数量[3041900001#b2]+银行业存款类金融机构协助扣划账户数量[3041900001#b3]";
	    	 String reg = "[u4e00-u9fa5]";
	    	 Pattern pat = Pattern.compile(reg);  
	    	 Matcher mat = pat.matcher(str); 
	    	 String repickStr = mat.replaceAll("");
	    	 System.out.println("去中文后:"+repickStr);
	}
		

}

结果是：去中文后:[3041900001#01]<=[3041900001#b1]+[3041900001#b2]+[3041900001#b3]
