New to Java

any kind soul can help me convert Java code to pseudo code??? My due is 20hrs later !!! please help

package assignment;

import javax.swing.JOptionPane;
import javax.*;
public class Array
{
public static void main (String args[])
{
int inputInt = 0;
String errorMsg;
String wanaPlayInput;

do{ //set the flag for input as true at first
boolean inputAgain = true;

while (inputAgain){
String tryInput = JOptionPane.showInputDialog("How many numbers do you want to enter");
try{
errorMsg = "";
inputInt = Integer.parseInt(tryInput);//try to change string into integer type
}
catch(Exception e){
errorMsg = e.getMessage();//input is not a number
//System.out.println("Exception!!" + errorMsg);
}
if(errorMsg.equals(""))//if no error msg, input is a number
inputAgain = false;//need not re-input
}

Double arrayInt [] = new Double [inputInt];

String numInputStr;
double numInput;
int pos;

for(int i=0; i<inputInt; i++){
pos = i + 1;
numInputStr = JOptionPane.showInputDialog("Enter number " + pos + " between 1 and 100");
numInput = Double.parseDouble(numInputStr);
while (numInput < 1 || numInput > 100){
//System.out.println("Number is less than 1 or more than 100");
numInputStr = JOptionPane.showInputDialog("Enter number " + pos + " between 1 and 100");
numInput = Double.parseDouble(numInputStr);
}
if(numInput > 0 && numInput < 101)
arrayInt[i] = numInput;
}

for(int j=0; j<inputInt; j++){
double number = arrayInt[j];

double squaredNum = calSquare(number);
//double squaredNum = Math.pow(number,2);
//System.out.println(number + " squared is : " + squaredNum);

JOptionPane.showMessageDialog (null, msgBox);
}
//System.out.println("I am outside the loop");

}
while (wanaPlayInput.equalsIgnoreCase("y"));
}
