z = mystery(y, x, y); // Statement 1

System.out.println(x + " " + y + " " + z); // Statement 2

x = mystery(z, y, x); // Statement 3

System.out.println(x + " " + y + " " + z); // Statement 4

y = mystery(z, y, y); // Statement 5

System.out.println(x + " " + y + " " + z); // Statement 6

}

public static int mystery(int z, int x, int y) {

z--;

x = 2 * y + z;

y = x - 1;

Dear Student ,

As per requirement submitted above kindly find below solution.

Below table shows the tracing.

x	y	z	method call	z	x	y	print statement in method call	return x	print x,y,z
1	2	3	z = mystery(y, x, y);	1	5	4	4 1	5	1 2 5
1	2	5	x = mystery(z, y, x);	4	6	5	5 4	6	6 2 5
6	2	5	y = mystery(z, y, y);	4	8	7	7 4	8	6 8 5

Below screen shows the output as per tracing
