Swap the operands under comparison

Swap the operands under comparison to prevent null pointer exception (at least in java)

Input

if(lang.equals("en_US")) {
	System.out.println("The lang is en_US i.e english US"+
}

if(lang.equals("es_US")) {
	System.out.println("The lang is es_US i.e spanish US"+
}

if(lang.equals("fr_US")) {
	System.out.println("The lang is fr_US i.e france US"+
}

Output

if("en_US".equals(lang)) {
	System.out.println("The lang is en_US i.e english US"+
}

if("es_US".equals(lang)) {
	System.out.println("The lang is es_US i.e spanish US"+
}

if("fr_US".equals(lang)) {
	System.out.println("The lang is fr_US i.e france US"+
}
