JAVA uses the try-catch statement to handle exceptions.
Place possible exception operations in the try part of try-catch. Once the try part throws an exception object, or calls a method that may throw an exception object, and the method throws an exception object , then try ends execution immediately and turns to the catch part. Therefore, the program places the processing after an exception occurs in the catah part.

Let’s look at the following example:
try{
包含可能发生异常的语句//正常业务逻辑代码
}
catch(ExceptionSubClass1 e){
...//当try发生异常,将执行catch代码,若无异常,不执行
}
catch(ExceptionSubClass2 e){
...
}Debugging:
public class text1
{
public static void main(String[] args)
{
int n=0,m=0,t=1000;
try
{
m=Integer.parseInt("8888");
n=Integer.parseInt("ab89");//发声异常,转向catch
t=7777;//t没有机会执行
}
catch(NumberFormatException e)
{
System.out.println("发生异常:"+e.getMessage());
}
}
}Run Result:
