I encountered the error'The MATLAB Editor requires Java.'
+ Java's version on my PC is
version -java
'Java 1.8.0_202-b08 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode'
And I have already installed the latest version of Java from Oracle.
The code I executed is shown below:
mywave.m
edit mywave
for i = 1:1024
A(i) = sin(i*2*pi/1024);
end
Untitled.m
job = batch('mywave')
wait(job)
load(job)
Error message in Command window is shown below:
Error using parallel.Job/load (line 36)
Error encountered while running the batch job. The error was:
Error using edit (line 73)
The MATLAB Editor requires Java.
Error in mywave (line 1)
The same issue occurred in both (R2024a) and (R2023a).

It appears there is an error occurring while following the "Run Batch Parallel Jobs" tutorial from MathWorks documentation.
This issue is not related to Java, as its installation has been confirmed. Instead, the problem seems to be with the implementation of the tutorial itself.
In the ‘mywave.m’ script, the line “edit mywave” is unnecessary if the script file has already been created. This line is typically used only for creating a new script file named ‘mywave’. If the file already exists, this line can be omitted.
To proceed, ensure that only the following code is present in the ‘mywave.m’ script:
for i = 1:1024
A(i) = sin(i*2*pi/1024);
end
By making these adjustments, the tutorial should run without issues.
Hope this helps.

Remove the first line,
edit mywave
