Syntax error on a for loop

Question

I am getting an error on the first line of the for statement. It says I need a semicolon but I can't seem to correct it and I know the error might not necessarily be on that line. I'm not sure how this even is going to print at the end of the switch statement but i can't compile it to find out. I can show you in another post what i am trying to achieve if it will help. Thanks.
import javax.swing.*;
import java.text.*;
public class printNum
public static void main (String [] args) {
String startNumStr, endNumStr;
int startNum, endNum;
startNumStr= JOptionPane.showInputDialog(null, "Enter a starting number:");
startNum = Integer.parseInt(startNumStr);
endNumStr = JOptionPane.showInputDialog(null, "Enter an ending number:");
endNum = Integer.parseInt(endNumStr);
for(int startNum < endNum) {
switch(startNum) {
case startNum + 10:
case startNum + 10:
case startNum + 10: System.out.println(" " + startNum); break;
default: System.out.println(" " + startNum);
}

int startNum, endNum;
startNumStr=
tNumStr= JOptionPane.showInputDialog(null, "Enter a

startNum = Integer.parseInt(startNumStr);
endNumStr = JOptionPane.showInputDialog(null,
og(null, "Enter an ending number:");
endNum = Integer.parseInt(endNumStr);
for(int startNum < endNum) {
switch(startNum) {
case startNum + 10:
case startNum + 10:
case startNum + 10:
e startNum + 10: System.out.println(" " + startNum);
break;
default: System.out.println(" " +
ut.println(" " + startNum);
}Why do you have the same case 3 times in the switch? Also, I don't think you can have variable expressions in the switch statement cases. I think these need to be constants.
