Program Limas dengan Java

just for fun if ya aja aja help make my friends who again butuhin yes even though the program immediately wrote a simple cuman
The first main function ne ane pake source:

package limassegi4;

public class Main {

public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable() {

public void run() {
new limasJFrame().setVisible(true);
}

});
}

}

It is a function mainya continues on to make a new Class of Class Java Class
and we nih content source:

package limassegi4;

public class limas {
//ATTRIBUT
private int panjang;
private int lebar;
private int tinggi;
private int alas;
private int diameter;

public limas(int p, int l, int t, int a, int d){
//KONSTRUKTOR
//PUBLIC LIMAS
this.panjang = p;
this.lebar = l;
this.tinggi = t;
this.alas=a;
this.diameter=d;
}

limas(int p, int l, int t) {
this.panjang=p;
this.lebar=l;
this.tinggi=t;
}
//AKSESOR
public int getLebar() {
return lebar;
}

public void setLebar(int lebar) {
this.lebar = lebar;
}

public int getPanjang() {
return panjang;
}

public void setPanjang(int panjang) {
this.panjang = panjang;
}

public int getTinggi() {
return tinggi;
}

public void setTinggi(int tinggi) {
this.tinggi = tinggi;
}
public int getAlas(){
return alas;
}
public void setAlas(int alas){
this.alas=alas;
}
public int getdiameter(){
return diameter;
}
public void setdiameter(int diameter){
this.diameter=diameter;
}
//METHOD
public float volume(){
double v = 0;
return(float) (0.33*(panjang*lebar)*tinggi);
}

public float luas(){
double luas = 0;
return(float) ((panjang*lebar)+(4*0.5*lebar*tinggi));
}

public int keliling(){
double kel = 0;
kel = Math.sqrt((Math.pow(Math.sqrt((Math.pow(panjang, 2)) +
(Math.pow(lebar, 2)))/2, 2)) + (Math.pow(tinggi, 2))) * 8;
return (int) kel;
}
}

when it's finished we just created jFramenya ahhiiiii
nih immediately wrote

Well presumably so n view of the GUI guess - something like ...

Good Luck.^_^
