A method that specifies that it can throw the exception. The method must provide a throws clause that lists the exception

Can someone show me the block of code which explains the try statement which catches the exception.
Also the method that specifies that it can throw the exception, this would be much appreciated

Code:

	public void catchexample(){
		try {
		
		//codehere
		
		} catch(IOException E){
			E.printStackTrace();
		}
	}

So thats block of code there is a try statement?
And thank you for taking the time to post it repped.

Code:

void test() throws Exception {
	if(var == null)
		throw new Exception("Var is null");
	System.out.println(var);
}

What the above method does is throw an Exception if the Object var is null, otherwise it will be printed to System.out

To catch any errors thrown by this method you can do this:

Code:

try {
		test();
} catch(Exception e) {
		System.out.println(e.getMessage());
}

what this will do is if test() throws an exception, the error message from the exception is printed to console.

Thank you very much king i now understand
repped

nvm.
