How to print underlined string in console output in java

Question

我想知道是否有任何方法可以使用 java String 类在控制台上打印带下划线的文本。

Answer 1

You can only rely on how the String is interpreted by your console. For example, in bash , you can do something like inserting your string between escape sequences \\033[1m and \\033[0m (for bold ):

\033[1mInsert your String here\033[0m

You should read the documentation of your favorite console.

Answer 2

I'd have a look at the tput command as outlined in this answer , but it will make your code a bit unreadable as it will look like this

System.out.println("...")
// execute tput
System.out.println("underlined text")
// execute tput
System.out.println("...")

Notice I'm assuming you aim for bash like terminal

I used Netbeans IDE v12.0

String txt="Welcome Back";
String utxt = String.join("\u0332",n.split("",-1));
System.out.println(utxt);

Output

W̲e̲l̲c̲o̲m̲e̲ ̲B̲a̲c̲k̲

result in IDE

On my IDE you can also use like the below Mentioned :

System.out.println("Underlined Text");
System.out.println("_______________")
