java - How to test percentage in an if statement? -

how can test percentage in if statement?

for example:          package walker;      public class walker {          int tuning = 10;          int speed = 0;          int gas = 100;          int energy = 100;          int time = 1;          int strecke = 0;          boolean test = true;          boolean beschleunigung = false;          walker() {             tuning = 10;             gas = 0;             energy = 100;         }               public void setgas(int x) {                  gas = x;              }               public void setspeed(int x) {                  tuning = x;              }               public void walk() {                  boolean walking = true;                  while (walking) {                       if (speed<10) {                          beschleunigung = true;                      }else {                          beschleunigung = false;                      }                      if (beschleunigung==true) {                          speed +=1+(tuning);                          energy -=1;                          }                      strecke = (speed*time);                      speed = (strecke/time);                      gas -= 1;                      energy -= 1;                      time +=1;                       if (gas<1||energy<1){                          break;                      }                      }              system.out.println("distance "+(strecke)+" meter");              system.out.println("gas left :"+gas);              system.out.println("energy left : "+energy);               }      } 

the _user able change value "tuning" , "gas"

and thats part add :

if (strecke==33%) { system.out.println("test"); } 

could me?

you're not using % correctly. in java % operator used find remainder. example following true:

0 == 6 % 3 (because 6 divided 3 has no remainder)

1 == 7 % 3 (because 7 divided 3 has remainder of 1)

if want convert gas percentage should dividing something. example:

if (gas / fulltank == 0.33)

however, need realize may never equal .33. want check see if it's <= .33. if so, print message , set boolean variable remember printed it.

also note if gas integer type need first convert float:

if ((float)gas / fulltank == 0.33)
