Call java method from batch file

This is what I have in Java: Runtime. Nathan 6, 6 6 gold badges 44 44 silver badges 66 66 bronze badges. Amara Amara Add a comment. Active Oldest Votes. Batch files are not an executable. They need an application to run them i. Paulo Guedes Paulo Guedes 6, 5 5 gold badges 39 39 silver badges 58 58 bronze badges. For me it says Windows cannot find "build. So where should I put this file? Or how should I give the path. Any suggestions? How can avoid that I mean executing all the commands on one window.

We have some code which is directly calling "gradlew. So I guess either Java or Windows fixed part of the problem at some point. If we try to exec "gradlew", that fails though, so clearly the ".

Also, the code for the batch file is running nicely, but I cannot get it to raise an error Exception. It'd drive me nuts to have such a confusing variable name as "is" in my code. Interesting choice to resurrect an old post ProcessBuilder offers more control, specifically the ability to easily redirect stderr to stdout. I also find the setup more intuitive, but that's a personal pref — basszero. To run batch files using java if that's you're talking about Abbia Abbia 1 1 silver badge 2 2 bronze badges.

The question was already answered with a working solution. You should offer only solutions you know are working and describe why you think your solution might be better.

So I guess the question is what OS are you using? Joanne Neal. So if you did something like java -cp Then write the data to a file as was suggested by Joe.

Thanks for that. Based on your inputs, here is what I have so far. The batch file echo off java -cp wcs-all When I tried running this, I get the following when something fails: java.

ExecutionException: java. ConnectException: Connection refused: no further information at sun. What is it? I'm not an expert in writing Windows batch files, but are you sure the syntax of this line is correct? Lookup the syntax. I made some changes and the batch file looks as below: echo off java -cp wcs-all Maybe another question that is somewhat related to what I'm trying to do here. How can I pass a parameter to a batch file. For example: myBatch. I have another question.

I have a call to a Java process like this in my batch file: java -cp MyMainClass How can I make the above call return control to the batch file that it is running from?

The choice of the number of parameters to use is up to you; use a comma to separate them. The method findProduct in the following example takes two integers as arguments.

When we call the method, we feed it two numbers that will be multiplied by each other inside the method:. When working with multiple parameters, the method call must have the same number of arguments as the parameters and pass the arguments in the same sequence.

When you execute a program, you may want to feed some information into it. It is performed by invoking main with command-line arguments. Below is an example showing all of the command-line arguments invoked.

Overriding is a concept that allows a subclass or child class to implement a method already offered by one of its super-classes or parent classes. When a method in a subclass has the same name, parameters, or signature, and return type or the sub-type as a method in its super-class, the subclass method is said to override the super-class method.

In other words, which version of an overridden method gets preference is determined by the type of the object being referenced to and not the type of the reference variable. Method overloading occurs when a class contains two or more methods with the same name but distinct parameters.

Overriding a given method means having the same name, number of parameters, type, etc. Consider the following example, which contains a single method for finding the numbers product of various types. If the number and type of parameters are different, many methods with the same name can exist. However, the parameters can still be variable. A method is a section of code that only executes when invoked.

It has parameters that refer to data that can be passed into a method. Methods, often known as functions, carry out specific tasks.

To reuse code, create it once and use it multiple times. The method has to be created within a class. That is where the method declaration exists. However, Java has several pre-defined ways, such as system. Save my name, email, and website in this browser for the next time I comment.
