个人原创代码：Java异常处理程序。编写Java Application程序，参考下面的程序，试修改程序，捕获相关异常，使得程序能正常运行。[提示：用错误数据测试，即可得到异常类名，运行时主方法参数输入 abc 测试]

public class StringIndexOutOf{

public static void main(String args[]){

System.out.println("字符串索引越界异常")

String str=args[0] System.out.println(“第四个字符为 ”+str.charAt(3))

int aa=Integer.parseInt(args[0]) System.out.println(“平方为 ”+aa*aa)

}

}-Personal original code: Java exception handling procedures.Write java application procedures, refer to the following program, try to modify the program to capture the relevant exception, makes the program run normally. Tip: test with the wrong data, you can get the name of the exception class, the main method arguments in the run-time input abc test]

public class StringIndexOutOf {

public static void main (String args []) {

System.out.println ("String index out of bounds exception")

String str = args [0]　System.out.println ("The fourth character is" the+ str.charAt (3))

an int aa = Integer.parseInt (args [0])　System.out.println ("square"+ aa* aa) of
