Output
Exception in thread “main” java.lang.ArithmeticException: / by zero
As displayed in the above example, the rest of the code is not executed (in such case, the rest of the code
statement is not printed).
There might be 100 lines of code after the exception. If the exception is not handled, all the code below the
exception won’t be executed.
Solution by exception handling
Let’s see the solution of the above problem by a java try-catch block.
Example 2
TryCatchExample2.java
public class TryCatchExample2 {
public static void main(String[] args) {
try
{
int data=50/0; //may throw exception
}
//handling the exception
catch(ArithmeticException e)
{
System.out.println(e);
}
System.out.println(“rest of the code”);
}
}
Output
java.lang.ArithmeticException: / by zero
rest of the code
As displayed in the above example, the rest of the code is executed, i.e., the rest of the code statement is printed.
Example 3
In this example, we also kept the code in a try block that will not throw an exception.
TryCatchExample3.java
public class TryCatchExample3 {
public static void main(String[] args) {
try
{
