Nesting try blocks should be
An example of a nested try block follows:
//Use a nested try block
class NestTrys {
public static void main (String args[ ]) {
//Here, numer is longer than denom
int numer[] = {4, 8, 16, 32, 64, 128, 256, 512};
int denom[] = {2, 0, 4, 4, 0, 8};
try {
//outer try block
for(int i = 0; i < numer.length; i++) {
try{
//the inner try block
System.out.println(numer[i] + "/" +
denom[i] + " is " +
numer[i] /denom[i]);
}
catch (ArithmeticException exc) {
//some code to tell the user what happened to cause the error
System.out.println("Can’t divide by Zero!");
}
}
}
catch (ArrayIndexOutOfBoundsException exc) {
the exception if the program tries to access an array index that doesn’t exist
//the code is specifically tailored to match the purpose of the program
System.out.println("No matching element found.");
System.out.println("Fatal error - - program terminated.");
}
}
}
