Short form for Java if statement
Use the ternary operator: I think you have the conditions backwards – if it’s null, you want the value to be “N/A”. What if city is null? Your code *hits the bed in that case. I’d add another check:

Read this thread R – boolean operators && and ||. Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.
Use -a (for and) and -o (for or) operations. tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html Update Actually you could still use && and || with the -eq operation. So your script would be like this: Although in your case you can discard the last two expressions and just stick with one or operation like this:
According to the C++ Standard 1 The && operator groups left-to-right. The operands are both contextually converted to bool (Clause 4). The result is true if both operands are true and false otherwise. Unlike &, && guarantees left-to-right evaluation: the second operand is not evaluated if the first operand is false. and 1 The || operator groups left-to-right. … Read more
The way it looks I think you’re not in a loop but just checking args in main. You probably want something like return 1 or exit(1) instead of the break.
You weren’t getting another input, or keeping count. Try this Output
Remove the semicolon at the end of this line: And please, please use curly brackets! Java is not like Python, where indenting the code creates a new block scope. Better to play it safe and always use curly brackets – at least until you get some more experience with the language and understand exactly when you can omit them.
You switched the operands in your assign statement. Switch this to this Math.abs(a[i]-a[i-1]) returns just an int value (no variable reference or similar). So your trying to assign a new value to a value. Which is not possible. You can just assign a new value to a variable.
You don’t necessarily need jQuery. JavaScript alone will do this. The c variable will be minor if the value is true, and major if the value is false. This is known as a Conditional (ternary) Operator. https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/Conditional_Operator
if is not a loop structure, so you cannot “break out of it”. You can, however, break out of the foreach by simply calling break. In your example it has the desired effect: Just for completeness for others that stumble upon this question looking for an answer.. break takes an optional argument, which defines how many loop structures it should break. Example: … Read more
