下列程序的功能是对两个整数进行比较，由考生通过输入窗口分别输入两个整数，程序比较出结果。例如：输入第1个整数为12，第2个整数为33。比较结果显示：12!=3312＜3312＜=33程序有多个遗漏和错误。本题要求改一个错，填三个空。注意：不改动程序结构，不得增行或删行。import javax.swing.JOptionPane;public class ex3{public static void main(String args[]){String firstNumber, //用户输入第1个字符串secondNumber, //户输入第2个字符串result; // a string containing the outputint number1， //较的第1个数number2; //的第2个数//读用户输入的第1个字符串read first number from user as a stringfirstNumber=JOptionPane.showlnputDialog("Enter first integer:");//用户输入的第2个字符串read second number from user as a stringsecondNumber=JOptionPane.showInputDialog("Enter second integer:");//字符串类型转换成整数类型number1=Integer.parseInt(firstNumber);number2=Integer.parseInt(secondNumber);result="";if(String.valueOf(numberl)=String.valueOf(number2))result=String.valueOf(numberl)+"= ="+String.valueOf(number2);if(String.valueOf(number1)!=String.valueOf(number2))result=String.valueOf(number1)+" !="+String.valueOf(number2);if(String.valueOf(numberl)＜ String.valueOf(number2))result=result+"\n" +String.valueOf(numberl)+"＜"+String.valueOf(number2);if(String.valueOf(numberl)＞String.valueOf(number2))result=result+"\n" +String.valueOf(numberl)+" ＞"+String.valueOf(number2);if(String.valueOf(numberl)＜=String.valueOf(number2))result=result+"\n"+String.valueOf(numberl)+" ＜="+String.valueOf(number2);if(String.valueOf(numberl)＞=String.valueOf(number2))result=result+"\n"+String.valueOf(numberl)+ "＞="+String.valueOf(number2);______(null,result，"比较结果"，______INFORMATION_MESSAGE);//程序正常退出______;}}
