SWITCH STATEMENT

Tell you secretly

This is my favourite topic among others! 😌

Let's begin!

1.

a. ( true ) && ( 3 > 4 ) – FALSE

b. ! ( x > 0 ) && ( x > 0 ) – FALSE

c. ( x > 0 ) || ( x < 0 ) – TRUE 

d. ( x != 0 ) || ( x = = 0 ) – TRUE

e. ( x >= 0 ) || ( x < 0 ) – TRUE

 f. ( x != 1 ) = = !( x = = 1 )- TRUE

2.

public class no2

public static void main(String[] args) {

int x=1, a=3;

switch (a) {

case 1: System.out.println (x+=5);

break;

case 2: System.out.println (x+=10);

break;

case 3: System.out.println (x+=16);

break;

case 4: System.out.println (x+=34);

}

3.

x=3;
y=3;
if (x+3==6)
{
