[英]Continue the execution after exception
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");
}
}
}
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");
}
}
}
当我运行此程序时,仅在检测到异常时才停止执行。 如何继续相同的执行while
异常后?
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;
}
}
}
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");
}
}
您需要确定何时将run
设置为false
