How to use subscript in java string?

问题

How can I write subscript characters in a Java string?

For example, I have to write "CO2". How can I move 2 to the bottom of CO?

回答1:

The String class doesn't provide such operations. But you could use the Unicode Character 'SUBSCRIPT TWO' (U+2082):

final String string = "CO\u2082"; // CO₂

Also, you could create a String as an HTML snippet. For instance,

final String html = "CO<sub>2</sub>";
