So I just installed JRE, JDK and Eclipse and I was trying to run this famous HelloWorld code, but it shows this message as in attached images. What's the ant build?

It looks like you don't have your file in your buildpath (what eclipse uses to figure out what files it should compile). Right click on the folder and select Buildpath -> Use as Source folder. Now when you hit run it should hopefully work.

看起来您的构建路径中没有您的文件（eclipse 使用什么来确定它应该编译哪些文件）。右键单击该文件夹并选择 Buildpath -> 用作源文件夹。现在当你点击运行它应该有希望工作。

Try to create a Java class file with suitable name and method.This error usually occurs when compiler doesn't understand which file to execute.

尝试用合适的名称和方法创建一个Java类文件。这个错误通常发生在编译器不知道要执行哪个文件时。
