The following console program uses parameters and produces eight lines of output. What are they?

public class ParameterMysterySection$2\{$

public static void main$($String$[]$ args$)\{$

int a $=137$;

int b $=42$;

$$

System.out.println$("$a $="+$ a$)$;

foo$($b$)$;

System.out.println$("$a $="+$ a$)$;

System.out.println$("$b $="+$ b$)$;

$$

a $=$ bar$($b$,$ a $+$ b$)$;

System.out.println$("$a $="+$ a$)$;

a $=$ bar$($a$,$ b$)$;

System.out.println$("$a $="+$ a$)$;

$\}$

$$

public static void foo$($int a$)\{$

System.out.println$("$a $="+$ a$)$;

a $=160$;

$\}$

public static int bar$($int c$,$ int b$)\{$

int d $=$ b $-$ c;

System.out.println$("$d $="+$ d$)$;

return d $\%10$;

$\}$
