Java输入与代码不匹配异常问题

Question

有点麻烦。

基本上，我得到了输入行

5,4,5 8,7=6,3 3,2 9,6 4,3=7,6=9,8=5,5 7,8 6,5 6,4

public class Pirate {

int singleCoordinateX;

    PrintStream out;
    String position;
    Coordinate coordinates;
    CoordinateRow newSplitStringRow;
    String splitString;
    CoordinateRow adjustedSplitStringRow;
    CoordinateRow newAdjustedSplitStringRow;

Pirate() {
out = new PrintStream(System.out);
position = "front";
        newSplitStringRow = new CoordinateRow();
        adjustedSplitStringRow = new CoordinateRow();
        newAdjustedSplitStringRow = new CoordinateRow();

            splitLineString(singleLineInputString);

                newSplitStringRow.addSingleCoordinateToBack(coordinates);
    
    
            }

        }

Answer 1

splitStringArrayScanner.useDelimiter(",");

splitStringArrayScanner.useDelimiter(",|\\s+");
