For the class Employee example provided in tutorial $3\mathrm{.}1\mathrm{.}7,$ what code segments could be added to keep track of the number of salary increases that have occurred for an employee using the variable salaryIncreases?

public void increaseSalary$($int percent$)\{$

if $($percent $>0)\{$

this.setSalary$($this$.$salary $+$ this.salary $*$ percent$)$;

this.salaryIncreases$+=1$;

$\}$else$\{$

System.out.println$("$Increase of salary must be greater than $0.")$;

$\}$

$\}$

public int getSalaryIncreases$($this$)\{$

return salaryIncreases;

$\}$

public void increaseSalary$($int percent$)\{$

if $($percent $>0)\{$

this.setSalary$($this$.$salary $+$ this.salary $*$ percent$)$;

this.salaryIncreases$+=1$;
