Java 异常后继续执行
我有两门课:Java 异常后继续执行,java,exception,loops,Java,Exception,Loops,我有两门课: 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
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");
}
}
}
主要问题是:
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");
}
}
}
当我运行这个程序时,当它检测到异常时,执行就会停止。如何在异常后继续执行相同的,
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;
}
}
}
这可能会有帮助
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;
}
}
}
将试扣移动到环内
boolean run = true;
while(run){
ex.a = --val;
try{
run = ex.operation();
}catch(RuntimeException e){
System.out.println("try exception");
}
}
您需要决定何时将
run
设置为false
。在循环中移动try catch
boolean run = true;
while(run){
ex.a = --val;
try{
run = ex.operation();
}catch(RuntimeException e){
System.out.println("try exception");
}
}
您需要决定何时将
run
设置为false
。将您的try/catch移动到while内。为什么将try/catch移动到while内?为什么将try/catch移动到while内?您知道,您的示例中有无限循环吗?将while(true)更改为while(status)对不起,我错了。我忘了改了。你知道吗,你的例子中有无限循环?将while(true)更改为while(status)对不起,我错了。我忘了换过了。
