ICSE Computer Application - Class X - 2017 PYQ

Name the operators listed below:

1. <
2. ++
3. &&
4. ? :

String x[] = {"SAMSUNG", "NOKIA", "SONY", "MICROMAX", "BLACKBERRY"};

Give the output of the following statements:

1. System.out.println(x[1]);
2. System.out.println(x[3].length());

Name the following:

1. A keyword used to call a package in the program.
2. Any one reference data type.

char ch='t';
res= Character.toUpperCase(ch);

int a,b;
for (a = 6, b = 4; a <= 24; a = a + 6)
{
    if (a%b == 0)
    break;
}
System.out.println(a);

x1= ++x – x++ + --x

int i = 1;
int d = 5;
do {
    d=d*2;
    System.out.println(d);
    i++ ; } while ( i<=5);

String s="Today is Test";
System.out.println(s.indexOf('T'));
System.out.println(s.substring(0,7) + " " +"Holiday");

What are the values stored in variables r1 and r2:

1. double r1 = Math.abs(Math.min(-2.83, -5.83));
2. double r2 = Math.sqrt(Math.floor(16.3));

String A ="26", B="100";
String D=A+B+"200";
int x= Integer.parseInt(A);
int y = Integer.parseInt(B);
int d = x+y;
System.out.println("Result 1 = " + D);
System.out.println("Result 2 = " + d);

Analyze the given program segment and answer the following questions:

for(int i=3;i<=4;i++ ) {
for(int j=2;j<i;j++ ) {
System.out.print("" ); }
System.out.println("WIN" ); }

1. How many times does the inner loop execute?
2. Write the output of the program segment.

char ch = 'F';
int m = ch;
m=m+5;
System.out.println(m + " " + ch);
