How to create a horizontal slider with custom min, max, and initial value in Java
While creating horizontal slider, we can set custom values as well. Let us take three integer variable and set the int values for min, max as well as the initial value of the slider −int val = 75; int min = 0; int max = 100;Set it to the slider while creating a new slider. Here, we have set the constant to be HORIZONTAL, since we are creating a horizontal slider −JSlider slider = new JSlider(JSlider.HORIZONTAL, min, max, val);The following is an example to create a horizontal slider with custom min, max and initial value −Examplepackage my; import java.awt.Color; import ...
