For new Java 8 Time API, you can use below code. You need to change DayOfWeek.THURSDAY etc in the below code.

LocalDate date1=LocalDate.now();
// This will give you int value of Day(for eg. Friday) and the date you want to check for

int duration=DayOfWeek.WEDNESDAY.getValue()-date1.getDayOfWeek().getValue();
System.out.println("duration "+duration);
if(date1.getDayOfWeek().equals(DayOfWeek.WEDNESDAY)) {
    System.out.println("Wednesday");
} else {
    date1=date1.plusDays(7).minusDays(7-  duration); 
}
// it will first give next day of week then minus the duration from 7.

System.out.println("new date1 "+date1);
