项目中要查父亲节，母亲节的节日，随手写了一个小方法，记录一下。

 

//能够用来计算父亲节 母亲节 感恩节等

//计算好比父亲节母亲节感恩节这种某个月的第几个周几的状况
private static String getCaculateDate(int n ,String rawWeek,String festWeek ) {
int a = 0;
String sDays = null;
if (rawWeek.equals("Mon")) {
a = 1;
}else if (rawWeek.equals("Tue")){
a = 2;
}else if (rawWeek.equals("Wed")){
a = 3;
}else if (rawWeek.equals("Thu")){
a = 4;
}else if (rawWeek.equals("Fri")){
a = 5;
}else if (rawWeek.equals("Sat")){
a = 6;
}else if (rawWeek.equals("Sun")){
a = 7;
}
int b = 0;
if (festWeek.equals("Mon")) {
b = 1;
}else if (festWeek.equals("Tue")){
b = 2;
}else if (festWeek.equals("Wed")){
b = 3;
}else if (festWeek.equals("Thu")){
b = 4;
}else if (festWeek.equals("Fri")){
b = 5;
}else if (festWeek.equals("Sat")){
b = 6;
}else if (festWeek.equals("Sun")){
b = 7;
}
int days = 0;
if (a == b) {
days = 7*(n-1)+b+(7-a+1);
}else if (a < b) {
days = 7*(n-1)-(7-b)+(b-a+1);
}else if (a > b) {
days = 7*(n-1)+b+(7-a+1);
}
if (days<10) {
sDays = "0"+days;
}else {
sDays = String.valueOf(days);
}
return sDays;
}
