How to use a java string method to return a selected amount of characters?

问题

我正在努力弄清楚如何在我的Java字符串中返回选定数量的字符。
在Python中,就像这样

String randomVar = "hello";
System.out.println(randomVar.substring(1));

输出将是 "ello"。

我如何在Java中实现相同的功能?
谢谢!

I am trying to figure out how to return a selected amount of characters in my java string.
In Python, it is just like

randomVar = "hello"
print(randomVar[1:])

and the output would be "ello".

How do I do the same thing in java?
Thank you!

这可以通过 substring() 实现。

String a = "hello";
System.out.println(a.substring(1, a.length()));

This can be accomplished with substring()

String a = "hello";
System.out.println(a.substring(1, a.length());
