Java Code: How to map a date with a quarter

This simple code will give you the quarter to which the provided date belong to. We need to provide the FY Start date too.

    public String getQuarter(Date date){
       
        int monthNo = date.getMonth();
        int year = date.getYear();
        int temp = year - 100;
        String quarterInfo = null;
        int fyStart = getFyStart(); //4 if fyStarts in April
        if (monthNo < fyStart) {
            monthNo = 12 + monthNo;
        } else {
            temp = temp + 1;
        }

        int q1End = fyStart + 3;
        int q2End = q1End + 3;
        int q3End = q2End + 3;
        int q4End = q3End + 3;

        if (monthNo >= fyStart && monthNo < q1End) {
            quarterInfo = "Q1" + " \'" + temp;
        } else if (monthNo >= q1End && monthNo < q2End) {
            quarterInfo = "Q2" + " \'" + temp;
        } else if (monthNo >= q2End && monthNo < q3End) {
            quarterInfo = "Q3" + " \'" + temp;
        } else if (monthNo >= q3End && monthNo < q4End) {
            quarterInfo = "Q4" + " \'" + temp;
        } else {
            quarterInfo = "None";
        }
        return quarterInfo;
    }

Hope this helps
