Explanation / Answer
According to this code:
if (y > z) {
a = y;
}
is the condition is which is correct
basically what this program does is reverse the string.
in while loop
x will be assigned with last value of the string.
output will concate the x value
n will exclude the last value of its value
Statement Program State int x = 15, y = 30, z = 10, a = 0;x = 15
y = 30
z = 10
a = 0 if ( x > y ) { x = 15
y = 30
z = 10
a = 0 if (x > z) { x = 15
y = 30
z = 10
a = 0 a = x; x = 15
y = 30
z = 10
a = 0 }
else { x = 15
y = 30
z = 10
a = 0 a = z;
x = 15
y = 30
z = 10
a = 0 }
}
else { x = 15
y = 30
z = 10
a = 0 if (y > z) { x = 15
y = 30
z = 10
a = 0 a = y; x = 15
y = 30
z = 10
a = 30 }
else { x = 15
y = 30
z = 10
a = 30 a = z; x = 15
y = 30
z = 10
a = 30 }
}
x = 15
y = 30
z = 10
a = 30 System.out.println("The value is: " + a); x = 15
y = 30
z = 10
a = 30
