We declare aListofStringobjects namednamesusing theArrayListimplementation. We then add threeStringobjects to the list using theadd()method. Thefor loopiterates through each element in thenameslist using the enhanced for loop (also known as the for-each loop) and assigns each element to a vari...
Now when I send a query the result set is so big, that I get java heap overflow. Is there any possibility to deal with such things. Does SQL have any kind of lineID so that I could iterate through the table. If there is no other possibility to solve the problem I have to insert...
One of the common problems many Java Programmers face is to remove elements while iterating over ArrayList in Java because the intuitive solution doesn't work like you just cannot go through an ArrayList using a for loop and remove an element depending upon some condition. Even though java....
SuperMerlin, I made some adjustments to your code to set the smooth property through Descriptors without selecting layers, and using the layerIds you gathered. it should be a bit faster #target photoshop if(documents.length) { var tLayers = getTextIds(); for(var a = 0; a...
