Determine output:

public class Test{
        public static void main(String args[]){
                int i; 
                for(i = 1; i < 6; i++){ 
                        if(i > 3) continue ; 
                }

What will be the output of the following program?

public class Test{
        public static void main(String args[]){
                int i = 0, j = 5 ;
                for( ; (i < 3) && (j++ < 10) ; i++ ){
                        System.out.print(" " + i + " " + j );
                }
                System.out.print(" " + i + " " + j );
        }
}

Consider the following program written in Java.

        public static void main(String args[]){
                int x=7; 
                if(x==2); // Note the semicolon
                System.out.println("NumberSeven");
                System.out.println("NotSeven");
        }
}

What would the output of the program be?

Determine output:

public class Test{
        public static void main(String args[]){
                int i, j;
                for(i=1, j=0;i<10;i++) j += i;
                System.out.println(i);
        }
}

What will be the output?

public class Test{
        public static void main(String[] args){
                int x=10, y=0;
                if(x && y){
                        System.out.print("TRUE");
                }
                else{
                        System.out.print("FALSE");
                }
        }
}

What will be the value of y after execution of switch statement?

public class Test{
        public static void main(String[] args){
                int x = 3, y = 4;
                switch(x + 3){
                        case 6: y = 0;
                        case 7: y = 1;
                        default: y += 1;
                }
        }
}

What is the printout of the following switch statement?

char ch = 'a';  
switch (ch){
      case 'a':
      case 'A': System.out.print(ch); break;
      case 'b':
      case 'B': System.out.print(ch); break;
      case 'c':
      case 'C': System.out.print(ch); break;
      case 'd':
      case 'D': System.out.print(ch);
}

How many times will the following code print "Welcome to Examveda"?

int count = 0;
do {
      System.out.println("Welcome to Examveda");
      count++;
} while (count < 10);

Choose the correct statement in context of the following program code.

public class Test{
      public static void main(String[] args){
            double sum = 0;
            for(double d = 0; d < 10;){
                  d += 0.1;
                  sum += sum + d;
            }
      }
}
