Java equivalent of Python's format()
提问by tshepang
Here's two ways of doing string substitution:
这是进行字符串替换的两种方法：
name = "Tshepang"
"my name is {}".format(name)
"my name is " + name
How do I do something similar to the first method, using Java?
如何使用 Java 执行类似于第一种方法的操作？

或更短：
MessageFormat.format("my name is {0}", name);

Underscore-java有一个format()静态方法。我是项目的维护者。活生生的例子
