try catch java example

Example 1: java try catch

try {
  // Code that may have error
} catch(ErrorName e){
  // Another code
}

Example 2: java try catch

try {
  // Code to try, which is throwing an Exception, e.g.
  /*example*/ Thread.sleep(100)
} catch (InterruptedException e /*Or any other exception*/) {
  // Handle Exception, usually:
  e.printStackTrace(); // Print the StackTrace of the exception to see what cause it
} finally {
  // Code executed after try / catch, used to close streams
  /*example*/ in.close();
}

Example 3: try block in java

try {
  //  Block of code to try
}
catch(Exception e) {
  //  Block of code to handle errors
}

Example 4: try catch java

public class MyClass {
  public static void main(String[ ] args) {
    try {
      int[] myNumbers = {1, 2, 3, 4, 5, 6};
      System.out.println(myNumbers[10]);
    } catch (Exception e) {
      System.out.println("Something went wrong. check again");
    }
  }
}

Example 5: exception handling in java example

public class Exception8 {
public static void main(String[]args)
{
   fun1();
   fun2();
}
static void fun1()
{
   	fun3();
}
static void fun2()
{
     	fun3();
}
static void fun3()
{
	try {
	System.out.println(20/0);
	}
	catch(ArithmeticException e)
	{
		System.out.println("Zero divison ");
	}
}
}

Example 6: try catch in java

try block: code that is protected for any exceptions. and it is mandatory 
(only try)
catch block: if any exception happens during runtime in the try block, 
the catch block will catch that exception.
if any exception happens during runtime in the try block, 
control will be given to catch block.
An optional finally block gives us a chance to run the code which 
we want to execute EVERYTIME a try-catch block is completed 
– either with errors or without any error.
