JAVA IF Else variables - 


public void actionperformed(actionevent arg0) {     string employeeinput;     string assetinput;      string userinput = txtuserinput.gettext();     userinput = userinput.tolowercase();      if (userinput.startswith("emp")){          //string employeeinput = null;         employeeinput = userinput.replaceall("\\s","");         txtuserinput.settext("");          joptionpane.showmessagedialog(frame, "the scan " );      }else if (userinput.startswith("u")){          assetinput = userinput;         assetinput.replaceall("\\s","");         txtuserinput.settext("");           system.out.println("employee id " + **employeeinput**); //asks employeeinput declared.          joptionpane.showmessagedialog(frame, "the scan " + assetinput);

i want employeeinput filled , saved, untill replaced employeeinput. problem i'm having when getting item input, employeeinput missing. way this?

thank you,

employeeinput method variable, everytime exit method lose reference it.

the obvious thing try turn employeeinput member variable. declare @ top of class.

better yet may persist value database.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
