Don't know about Spring class of java

[Sarfaraj Khan]

Hello Friend,

I have to discuss one of my query related to the java classes. I want to be aware about the 'Class Spring' of java. I don't any idea about the use of Spring class of java. I only know that, Spring class of java is related to the something about the properties. If you have enough knowledge about the Spring class of java, then please share it with me. I would appreciate your help greatly.

Hi Friend,

Spring class of java is essential to store varies properties that are used for it's behavior characterization. Spring class of java is basically extended from java package known as 'java.lang.Object'. The Spring class of instance useful for to mechanical spring visualization. This mechanism is very useful to make corrective force for the spring behavior. The spring class of java normally taken from 'javax.swing.Spring' package.

An instance of the Spring class holds three properties that characterize its behavior: the minimum, preferred, and maximum values. Each of these properties may be involved in defining its fourth, value, property based on a series of rules. An instance of the Spring class can be visualized as a mechanical spring that provides a corrective force as the spring is compressed or stretched away from its preferred value.

Hi,

I suggest you to refer following methods of the 'Spring class':

• height(Component cm)
• scale(Spring sp, float fr)
• setValue(int val)
• constant(int minm, int prefr, int maxm)
• constant(int prefr)

Example of Spring class of java:

class Spring {
    private static SpringFactory s_factory1 = new SpringFactory();
    public static SpringFactory getFactory() {
        return s_factory1;
    } 
    public Spring(ForceItem fi1, ForceItem fi2, float k, float len) {
        item1 = fi1;
        item2 = fi2;
        coeff = k;
        length = len;
    }
    public ForceItem item01;
    public ForceItem item02;
    public float length;
    public static final class SpringFactory {
        private ArrayList springs = new ArrayList();
        public Spring getSpring(ForceItem f01, ForceItem f02, float k, float length) {
            if ( springs.size() > 0 ) {
                Spring si = (Spring)springs.remove(springs.size()-1);
                si.item01 = f01;
                si.item02 = f02;
                si.coeff = k;
                si.length = length;
                return s;
            } else {
                return new Spring(f1,f2,k,length);
            }
        } 
        public void reclaim(Spring s) {
            si.item1 = null;
            si.item2 = null;
            if ( springs.size() < maxSprings )
               springs.add(s);
        }     }
}
