Question

I want put value of a at {0}. With C#, I code as:

String a="123"
String b="Xin chao: {0}, ban the nao";
String c=String.Format(b,a);

But in Java I don’t know. Can you help me?

Answer 1

Java’s counterpart is java.text.MessageFormat that allows placeholders like the one in your question can be replaced using format method as

String a = "123";
MessageFormat.format("Xin chao: {0}, ban the nao", a);
