The path of Java Learning (ii) Flow control statements

If, if...else ... Statement

        if (true) {            System.out.println ("execute when True");         Else {            System.out.println ("execute when false");        }

Switch statement

 switch   (a) { case  1:  switch  System.out.prin            TLN ("perform"  break  ;  case  2: System.out.println ( "Duty            The ");         break  ;  default  : System.out.println ( "when            ");         break  ; }

Break and continue can achieve sequential interrupts, but there are different jumps

Break: Force the program to interrupt the loop to leave the loop body;

Continue: Forcing the program to jump to the beginning of the loop, the statement after the continue statement will no longer execute, jump out of this cycle;

While statement

         while (a<100) {            // determine if the statement in white brackets is true, and execute the method in {} When it is true             System.out.println (a);            A+ +;        }

Do...while ... Statement

         Do {            // the statement in do inside is executed first to determine if the while statement is true             System.out.println (a);            A+ +;            System.out.println (a);          while (a<100);

For loop

 for (int i = 0; i < args.length; i++) {            }

99 Multiplication Table

 for (int i = 1; I <= 9; i++) {            for (int j = 1; J <=i; J + + ) {                System.out. Print (J+ "*" +i+ "=" + (i*j) + "\ T");            }            System.out.println ("\ n");        }
