Answer 1

The method FontMetrics.stringWidthdoes just that - it will return the width in pixels for the given one String.

Can be obtained FontMetricsfrom the Graphicsobject getFontMetrics.

For example:

g.setFont(new Font("Serif", Font.BOLD, 24));
int width = g.getFontMetrics().stringWidth("Hello World!");

System.out.println(width);

The result is:

135

In the Font class , you have methods like getLineMetrics or getStringBounds that can help you.
