Can we make a Java program by which just on one click it would check whether JRE is installed in the system or not? If not, then the program automatically downloads and installs JRE in the computer.

No. If the computer doesn't have a Java runtime installed, then no Java code can run.

You would need to create a "bootstrapper" application in a low-level language like C. And you would almost certainly need a different bootstrapper for each OS you wanted to support.
