Answer 1

Copy JDK directory to your STS installation or extraction library and and rename JDK to jre. the directory structure of STS should look like this

.eclipseproduct
artifacts.xml
configuration
dropins
eclipsec.exe
features
jre
license.txt
META-INF
open-source-licenses.txt
p2
plugins
readme
SpringToolSuite4.exe
SpringToolSuite4.ini
