so far i got something like... import java.awt.*; import javax.swing.*; public class MainGUI extends JFrame { JDialog welcome Window; public MainGUI() { super(); // unnecessary codes, no problem here } public void initComponents() { this.welcomeWindow = new JDialog()...

thx wave ^_^ and can someone actually teach me.. how to retrieve a string data from MySQL database, and display it in a swing GUI JDialog?? pop-up and a swing GUI that displays some particular information from MySQL database (in table)

so far.. i got String sql = "CREATE TABLE " + tableName + "(" + columnNames + " VARCHAR(32))"; i know it's wrong , but then not sure how i should write it... another word... stucked :)

need help with some coding public void createTable(String tableName, String[] columnNames, String[] columnType, String[] Keys) throws SQLException { try { stmt = conn.createStatement(); String sql = <need help here> stmt.executeUpdate(sql); }...

i was preparing for my compsci exam doing past papers and encountered a few questions i don't get can someone help me please? The following bytes are encountered in a UTF8 stream. What is the corresponding UCS2 code? (Express your answer in hexadecimal) 23 E8 96 BC C2 8B i don't know...

hello everyone, thanks for taking ur time reading this po i need help with something to do with java, designing an application to read sentences & words from a txt file, and create a new txt file, with all the words (in single) from the original txt file, next to each word, containing the...

i've derived the other formulae but I'm still stuck on this one, Koenig's Aparatus formula here's a picture of it with the formula need to derive into theta = h / [2(d+2D)]

for arranging the order for three beams for Round beam, i have I = A^2 / 12 Square beam, i have I = A^2 / 12 with equation C = YI / r Round beam will have r = YI / C = [Y*(A^2 / 12)] / C Square beam will have r = YI / C = [Y*(A^2 / 12)] / C but i don't know how to convert the...

Hello again, I don't understand how to derive equations. #1 C = YI / r Y = Young's modulus of the material r = radius of curvature of the neutral surface I = geometrical moment of inertia of the cross section of the beam C = bending moment #2 I = wt^3 / 12 I = moment of inertia...

can someone help me see if these look right? π = pi 0 < x < 3L ; 0 < y < 2L E1 + E2 = E Eigenvalue : ψ(x,y) = A sin [(n1 π x) / (3 L)] sin [(n2 π y) / (2 L)] Eigenfunction : E = E1 + E2 = [(n1^2 π^2 ħ^2) / (6 m L^2)] + [(n2^2 π^2 ħ^2) / (4 m L^2)] E = [(π^2 ħ^2) / (2 m L^2)] *...

i don't understand when it comes into 2 dimension :(

let's say.. there is a particle, with mass m, in a 2-dimensions x-y plane. in a region 0 < x < 3L ; 0 < y < 2L how to calculate the energy eigenvalues and eigenfunctions of the particle? thx :smile: and.. 2nd question.. there is a particle of kinetic energy E is incident from...
