//----------------------------一个字符串替换的函数
public static java.lang.String replace(java.lang.String strSource,java.lang.String strFrom,java.lang.String strTo){
java.lang.String strDest = "";
int intFromLen = strFrom.length();
int intPos;
while((intPos=strSource.indexOf(strFrom))!=-1){
strDest = strDest + strSource.substring(0,intPos);
strDest = strDest + strTo;
strSource = strSource.substring(intPos+intFromLen);
}
strDest = strDest + strSource;
return strDest;
}
public static java.lang.String replace(java.lang.String strSource,java.lang.String strFrom,java.lang.String strTo){
java.lang.String strDest = "";
int intFromLen = strFrom.length();
int intPos;
while((intPos=strSource.indexOf(strFrom))!=-1){
strDest = strDest + strSource.substring(0,intPos);
strDest = strDest + strTo;
strSource = strSource.substring(intPos+intFromLen);
}
strDest = strDest + strSource;
return strDest;

可以用StringBuffer，StringBuffer中用replace方法

public static String replaceString(String srcStr,String fromPattern,String toPattern) {
if(srcStr==null||fromPattern==null||toPattern==null)
return srcStr;
StringBuffer sb = new StringBuffer();
StringTokenizer token = new StringTokenizer(srcStr,fromPattern);
int size = token.countTokens();
if(size==0)
return srcStr;
for(int i=0;i<size;i++) {
sb.append(token.nextToken());
if(i<size-1)
sb.append(toPattern);
}
return sb.toString();
}
if(srcStr==null||fromPattern==null||toPattern==null)
return srcStr;
StringBuffer sb = new StringBuffer();
StringTokenizer token = new StringTokenizer(srcStr,fromPattern);
int size = token.countTokens();
if(size==0)
return srcStr;
for(int i=0;i<size;i++) {
sb.append(token.nextToken());
if(i<size-1)
sb.append(toPattern);
}
return sb.toString();
}
