java - how to code it to get pass error in method -

basically trying build calculator allow user take 1-5 options of multiplying, subtracting, multiplying, or dividing. whatever choose, inquire them come in 2 numbers after selecting function want. trying set bit calculation bit below running error here, not sure how should formatted. @ part of code receiving error.

inputoperation = myselection.selectionone().equals("5"); //this getting error "cannot convert boolean int"

the part trying insert in below code (i think):

public class selection { scanner readinput = new scanner(system.in); string selectionone() { string input; { //do loop go on run until user enters right response system.out.print("please come in number between 1 , 5, addition, s subtraction, m multiplication, or d division, or x exit: "); seek { input = readinput.nextline(); //user come in response if (input.equals("a") || input.equals("s") || input.equals("m") || input.equals("d") || input.equals("x")) { system.out.println("thank you"); break; //user entered character of a, s, m, or d } else if (integer.parseint(input) >= 1 && integer.parseint(input) <= 5) { system.out.println("thank you"); break; //user entered number between 1 , 5 } else { system.out.println("sorry, have not entered right number, please seek again."); } continue; } grab (final numberformatexception e) { system.out.println("you have entered invalid choice. seek again."); continue; // loop go on until right reply found } } while (true); homecoming input; }

.

public class answers { public float answer(int choice, float [] f){ float result = 0.00f; switch (choice){ case 1: result = f[0]+f[1]; break; case 2: result = f[0]-f[1]; break; case 3: result = f[0]*f[1]; break; case 4: result = f[0]/f[1]; break; case 5: system.out.println("you exting programme \n"); break; default: system.out.println("cannot calculate.\n entered" + choice); break; } homecoming result; } public static void main (string args[]){ int inputoperation; selection myselection = new selection(); inputoperation = myselection.selectionone().equals("5"); //this getting error "cannot convert boolean int" symbol.newsymbol("you entered selection of " + inputoperation + " successfully\n\n"); symbol.displaysymbol(); float [] myfloats = myselection.picknumbers(inputoperation); symbol.newsymbol("you entered " + myfloats[0] + " , " + myfloats[1] + " successfully\n\n") ; symbol.displaysymbol(); } }

.equals("") method homecoming boolean value.

you trying store boolean value in int variable (inputoperation).

c - Compilation of a code: unkown type name string - i have next lines of code compiler says following: "unknown type name 'string'" both in declaration , definition of function. can tell me what's wrong? thanks. #include <stdio.h> #include <stdlib.h> #include <string.h> void frecognizeclient(string *actualclient) there no string type in c. need utilize array so: char array[10]; then can pass in function: void frecognizeclient(char *actualclient); c arrays string compilation

java - Bypassing "final local variable defined in an enclosing type" - i'm writing programme , i'm getting "the final local variable asd cannot assigned, since it's defined in enclosing type". i provide illustration not code produces error aswell. have arraylist utilize later (if define within button can't utilize later on), outside of button, pressing button should give values arraylist. in illustration "create new arraylist" cause same problem. button btn = new button("asd"); final arraylist asd = new arraylist(); btn.setonaction(new eventhandler<actionevent>() { public void handle(final actionevent event) { asd = new arraylist(); //here's error.. } }); clear arraylist , add together values. java javafx
