一串数字中的逗号分隔符

试试这个,

String data="{4,15,26,7}";
data=data.substring(1,data.length-1);
String[] digits=data.split(",");
his.points=new ArrayList<Integer>();
    for (int i = 0; i < digits.length; i++) {
            this.points.add(Integer.parseInt(digits[i]));
    }

这并没有那么难。以下是我的消息来源: http://javarevisited.blogspot.nl/2011/09/string-split-example-in-java-tutorial.html

Determine if a String is an Integer in Java

所以你想做的是:

points = new ArrayList<Integer>;
String foo = "4,15,10,100";
String[] splits = foo.split(",");

for(String temp : splits){
if(Character.digit(temp)) points.add(Integer.parseInt(temp);
}
