If you see stratus clouds, that's the time to get inside and stay there. Stratus clouds mean rain if it is warm and snow if it is cold. They look like a huge gray blanket that hangs low in the sky. Sometimes stratus clouds are on the ground or very near the ground, and then we call them fog. Usually stratus clouds and fog form when it has been cold out and then warmer, wet air blows in. As the warm air flows over the cold ground or over the cold air near the ground, the water vapor in the warm air condenses into drops of water that make a cloud.

This option is an abbreviation for-classpath. For very special cases, both java and javac have options that let you change the path they use to find their own class libraries.
