Run two JARS sequentially one after another using a BATCH file

I need to execute 2 jars files in sequence order. number1.jar need to run and finish its execution before number2.jar is executed.

How could I achieve this 开发者_StackOverflow中文版using a BATCH file under a Windows environment?

java -jar number2.jar
