The algorithm checks if the values in the array are in increasing order

The algorithm sorts the value in decreasing order

The algorithm sorts the value in increasing order

Trace the following code, what is the output?

boolean flag = false;

int a[] = new int[10];

int i = 1;

while(!flag) {

a[i] += i;

if (i >= a.length){

flag = true;

}

System.out.println(a[i]);

i++;

}

There is a syntax error

Output will be:

Out of bounds exception

Output will be:

Output will be:

for(int i = a.length-1; i >= 0; i-=2) {

Trace the following code, what is the output?

int a[] = new int[10];

a[i] += i ;

System.out.println(a[i]);

for ( int j = 5; j<=10; j++)
System.out.println(i + " , " + j);

How many iterations will be performed in total when executing the following java-code:

for(int i=0;i<5;i++)

i++; System.out.println(i);

What will happen when you attempt to compile and run the following code in a method?

for(int i=0;i<5;)

{

}

The program will return a runtime error

The program will print numbers from 0 to 4

The program will return a compilation error

The program will print numbers from 1 to 5

Match the repetitions and numbers of their iterations:

int x = 13, y = 0; while(x>y) { x--; y++; }

for (int j = 5; j > 0; j--) System.out.println("j = " + j);

int i = 5; while(i>=0) --i;

int counter = 10; do counter++; while(false);

while (true) System.out.println("Hello World!");

Variables declared inside the repetition block are accessible from the rest of the program.

True

False

What will be printed on the output after the execution of Java-code below:

Personal data: Name - John Smith, Address - Road 2002, Block 123

Personal data: Name - John Smith

Personal data:

No output
