Extracting integers from strings in java is too inefficient to compare strings one by one, so you need to use regular expressions for matching, as shown in the following code:

String? str？ =? "Amount: 88,687,594 yuan";

Pattern? p？ =? Pattern.compile("\\d+(，\ \ d { 3 })*)；

Stick figure? m？ =? p . matcher(str)；

if(m.find()){

system . out . println(m . group())；

}
