[英]Continue the execution after exception
I have these two Class : 我有这两个类:
public class TryException {
int a=0;
TryException(int c) {
a = c;
}
public boolean operation() //just example
{
if(a!=10)
{
System.out.println(a);
return true;
}else{
throw new RuntimeException("display something");
}
}
}
and the main : 和主要:
public class Test {
static public void main(String args[])
{
int val =20;
TryException ex = new TryException(val);
try{
while(ex.operation()){
ex.a = --val;
}
}catch(RuntimeException e)
{
System.out.println("try exception");
}
}
}
when i run this program, the execution is stoped just when it detects the exception. 当我运行此程序时,仅在检测到异常时才停止执行。 How to continue the execution of the same
while
after exception ? 如何继续相同的执行
while
异常后?
It may help... 这可能会帮助...
public class Test {
static public void main(String args[])
{
int val =20;
TryException ex = new TryException(val);
boolean status = true;
while(status){
try{
status = ex.operation();
} catch(RuntimeException e) {
status = true; //Or whatever...
}
ex.a = --val;
}
}
}
Move the try-catch inside the loop. 在循环内移动try-catch。
boolean run = true;
while(run){
ex.a = --val;
try{
run = ex.operation();
}catch(RuntimeException e){
System.out.println("try exception");
}
}
You need to decide when to set run
to false
... 您需要确定何时将
run
设置为false
...
