method1()

will not catch the error if you haven't re-tossed it from block catch

to method2()

.



void method2() {
    try {
        // Error here
    } catch(Exception e) {
        throw e;
    }
}

If you have thrown another exception in the catch2 block of method2.



public void method2() {
    try {
        // ...
    } catch(Exception e) {
        throw new NullPointerException();
    }
}

    public void method1(){
        try {
            test2();
        } catch (IOException ex) {
            //catch test2() error
        }
    }

    public void method2() throws IOException{

    }

Use throws

This won't happen until you drop it into catch

your block by method2

adding throw e;

.
