Problem understanding a java statement!

[Moham12345]

Please could somebody help me understand what this statement is doing,

k = (k1 > s0) ? k1 : s0;

what is this statement doing?

what will k be equal to if
k1 = 3 and s0 = 2 ?

k = (k1 > s0) ? k1 : s0;

what is this statement doing?

if (k1 > s0) {
k = k1;
} else {
k = s0;
}

Or, assuming suitable types:

k = Math.max(k1, s0);

The trick is in understanding the ternary operator,

? :

This takes three operands,

<op1> ? <op2> : <op3>


op1 must have a boolean type; op2 and op3 must have compatible types.

The value of the expression is op2 if op1 is true, op3 otherwise.
