查找字符串中的数字

查找字符串中的数字

String numStr = "0123456789"；
int index = 0;
		for(int i=0;i<numStr.length();i++){
			while((index = str.indexOf(numStr.charAt(i), index)) != numStr.length()){
				if(index == -1)break;
				result[str.length()-index-1] = String.valueOf(str.charAt(index));
				++index;
			}
		}

更改的数字转中文大写代码

package zeng.test;

public class Num2CnNum {
	
	private static final String cnNum1[] = {"零","壹","贰","叁","肆","伍","陆","柒","捌","玖"} ;
