Methods and arrays in java -


how pass array method can use method in switch statement in method?

package assignment8exam;  import java.util.scanner;  /**  *  * @author anders  */ public class course {      scanner sc = new scanner(system.in);      public void mainmenu() {          system.out.println("enter data studen, start entering how many");          int numbers = sc.nextint();// amount of student          (int = 0; < numbers; i++) {              system.out.println("enter name of student");             scanner name = new scanner(system.in);              string names = name.nextline();             string studentnames[] = new string[numbers];         }          (int j = 0; j < numbers; j++) {              system.out.println("enter grade of student");             scanner gradesc = new scanner(system.in);              int grade = gradesc.nextint();             int studentgrade[] = new int[numbers];         }          system.out.println("what want");         system.out.println("exit application 1");         system.out.println("print out names of students 2");         system.out.println("print out grades of students 3");         system.out.println("print out pairs consisting of “name­grade 4");          scanner choice = new scanner(system.in);         int order = choice.nextint();          switch (order) {              case 1:                 system.exit(1);             case 2:                 printoutnames(numbers); /* can use 1 studentname array*/          }     }      public void printoutnames(int numbers) {          (int = 0; < numbers; i++) {              system.out.println(studentnames[i].length); // how activate array studentnames??          }      } }

unless i'm missing big, arn't ever setting studentname array new array every time.

string studentnames[] = new string[numbers];

your setting blank array each time.

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.
