How to remove characters after space in java

Question

How can I do this in Java or Android like:

textView.setText("Hi " + name);
// I want only "Jhon" not "Doe"

I want only first name ("Jhon") not last name ("Doe")

Just use the java .split() function. It gives an array, with parts of the name, split by a space.

String name = "Jhon Doe";
String[] parts = string.split(" ");
textView.setText("Hi " + parts[0]);

Use can try below code

String name = "Jhon Doe";
String[] separated = currentString.split("\\s+");
String name =  separated[0]; // this will contain "Jhon"

You can use Java.String.split()

String string = "Jhon Doe";
String[] parts = string.split(" ");
String name = parts[0]; // Jhon
String surname = parts[1]; // Doe
textView.setText("Hi " + name);

Answer 5

If you prefer regex why not

String firstName = "John Doe".replaceFirst("^(\\w+).*$","$1")

Have fun.
