public class Scheduler {

private String description;

@NotNull
private Boolean sMondays;

@NotNull
private Boolean sTuesdays;

@NotNull
private Boolean sWednesdays;

@NotNull
private Boolean sThursdays;

@NotNull
private Boolean sFridays;

@NotNull
private Boolean sSaturdays;

@NotNull
private Boolean sSundays;

public Scheduler() {

}
}

||

public boolean validateAtLeastOneIsTrue() {
    return getsMondays() || getsTuesdays() || getsWednesdays()
    || getsThursdays() || getsFridays() || getsSaturdays()
    || getsSundays();
}
