Evaluating many expressions at once in Intellij Idea

Question

In Intellij Idea, I\'m looking for a way to evaluate many expressions in debug mode with one command.

Normally I can evaluate single command with Right Click →

Answer 1

well i was also struggling a lot with this, until i figured out that in the code it needs fully qualified paths for classes (for classes outside of java.*)

for example in this code below , i needed to find out , xml string representation from the document object (doc is my document object)

so i had to put this code into evaluate tab , which you can open from run window -after putting in below expression and clicking on evaluate - my xml string was printed in console

    javax.xml.transform.TransformerFactory tf = javax.xml.transform.TransformerFactory.newInstance();
    javax.xml.transform.Transformer transformer = tf.newTransformer();
    java.io.StringWriter writer = new java.io.StringWriter();
    transformer.transform(new javax.xml.transform.dom.DOMSource(doc), new javax.xml.transform.stream.StreamResult(writer));
    System.out.println(writer.getBuffer().toString());

Answer 2

You can evaluate such expressions in Evaluate window

System.out.println(myVar1);
System.out.println(myVar2);

The only thing here is that your whole result (not last) will appear not in the same window but in a console.

Answer 3

You have to click "Code fragment mode" in the evaluate expression dialog (Alt+F8) and you can enter as many lines as you want instead of single line - which is default - "Expression mode".

Then you can switch back anytime using "Expression mode" button.

Answer 4

You can either click the small fullscreen arrows button to the right of the Expression box, or press shift+enter.

If you want to edit a multi-line expression or a code fragment, click Expand in the Expression field or press ⇧⏎ to switch to the multi-line Code fragment view and back.
