Which “if” construct is faster - statement or ternary operator?

Question

There are two types of if statements in java - classic: if {} else {} and shorthand: exp ? value1 : value2. Is one faster than the oth

Answer 1

Ternary operator is faster than if-else condition.

public class TerinaryTest {
    public static void main(String[] args)
    {
        int j = 2,i = 0;
        Date d1 = new Date();
        for(long l=1;l<100000000;l++)
            if(i==1) j=1;
                else j=0;
        Date d2 = new Date();
        for(long l=1;l<100000000;l++)
            j=i==1?1:0;
        Date d3 = new Date();
        System.out.println("Time for if-else: " + (d2.getTime()-d1.getTime()));
        System.out.println("Time for ternary: " + (d3.getTime()-d2.getTime()));
    }
}
