spark-3.0.1-bin-hadoop2.7 failed to launch, java: No such file or directory

Whenever I approach to java, I have some problems.
(To use tensorflowonspark, I run the code)

At windowpowershell,

export JAVA_HOME=/mnt/c/Program\ Files/Java/jdk1.8.0_261

 ${SPARK_HOME}/sbin/start-master.sh

starting org.apache.spark.deploy.master.Master, logging to /mnt/c/Users/MY_PATH/spark-3.0.1-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.master.Master-1-DESKTOP-5CGUHKF.out

IN JAVA, THERE ISN'T ANY "java" FILE! HOW CAN I SOLVE IT?

java.exe does exist in your output

You've installed Java for Windows, but using Shell scripts, which will not work together.
