java怎么将字符串转为数值型,java将数字字符串转化为数字

int a = 2000;
String str = NumberFormat.getIntegerInstance(Locale.getDefault()).format(a); //转为千分符字符串
System.out.println(str);

try {
int b = NumberFormat.getIntegerInstance(Locale.getDefault()).parse(str).intValue(); //转为数字
System.out.println("" + b);
} catch (ParseException e) {
e.printStackTrace();
}
