java - .jar from netbeans will not open in console -


built simple java program in netbeans, build/compiled , generated .jar me in project directory.

the following src code:

    import java.util.scanner;  public class welcome {     public static void main(string[] args){          system.out.println("welcome java");         scanner input = new scanner(system.in);      }  }

i want able open in console use scanner function, can't seem open jar.

i have tried opening command line following:

java -jar "c:\users\nick\documents\netbeansprojects\javaapplication1\dist\javaapplication1.jar"

but no dice. double clicking .jar doesn't open either.

any ideas here?

regards

you need build runnable jar if want start -jar

see https://docs.oracle.com/javase/tutorial/deployment/jar/run.html

you can run jar packaged applications java launcher (java command). basic command is:

java -jar jar-file

the -jar flag tells launcher application packaged in jar file format. can specify 1 jar file, must contain of application-specific code.

before execute command, make sure runtime environment has information class within jar file application's entry point.

to indicate class application's entry point, must add main-class header jar file's manifest. header takes form:

main-class: classname

the header's value, classname, name of class application's entry point.

the alternative run using specifying classpath , main class

java -cp "c:\users\nick\documents\netbeansprojects\javaapplication1\dist\javaapplication1.jar" welcome

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.
