Check if an Interval (time) is contained in another (java)

June 18, 2010 by campa

Here how I check if a Interval (time) is contained into another.

import org.apache.commons.lang.math.LongRange;
import org.apache.commons.lang.math.Range;
...

externalBeginDate = new java.utilDate();
...
Range externalRange = new LongRange(externalBeginDate.getTime(),externalEndDate.getTime());
Range internalRange = new LongRange(internalBeginDate.getTime(),internalEndDate.getTime());

if (externalRange.containsRange(internalRange)) {
			//ok internal range is internal 
}
