This blog explains about RYTWAYS Fresher Interview Questions with Answers – Part 3 and is given below :

We have already discussed about some questions in the previous part 1 & 2

11. Write a Java program to transpose a matrix .

Java Program to transpose matrix

Converting rows of a matrix into columns and columns of a matrix into row is called transpose of a matrix.

Let’s see a simple example to transpose a matrix of 3 rows and 3 columns.

publicclass MatrixTransposeExample{
publicstatic void main(String args[]){
//creating a matrix
intoriginal[][]={{1,3,4},{2,4,3},{3,4,5}};
//creating another matrix to store transpose of a matrix
inttranspose[][]=new int[3][3]; //3 rows and 3 columns
//Code to transpose a matrix
for(inti=0;i<3;i++){
for(intj=0;j<3;j++){
transpose[i][j]=original[j][i];
}
}
out.println(“Printing Matrix without transpose:”);
for(inti=0;i<3;i++){
for(intj=0;j<3;j++){
out.print(original[i][j]+” “);
}
out.println();//new line
}
out.println(“Printing Matrix After Transpose:”);
for(inti=0;i<3;i++){
for(intj=0;j<3;j++){
out.print(transpose[i][j]+” “);
}
out.println();//new line
}
}}

Output:

Printing Matrix without transpose:1 3 4 2 4 3 3 4 5

Printing Matrix After Transpose:1 2 3 3 4 4 4 3 5

12 . Write a Java program to swap two numbers without using temporary variable .

Write a program to swap or exchange two numbers without using any temporary or third variable to swap.

Code:

package com.java2novice.algos;

public class MySwapingTwoNumbers {

public static void main(String a[]){

int x = 10;

int y = 20;

System.out.println(“Before swap:”);

System.out.println(“x value: “+x);

System.out.println(“y value: “+y);

x = x+y;

y=x-y;

x=x-y;

System.out.println(“After swap:”);

System.out.println(“x value: “+x);

System.out.println(“y value: “+y);

}

Output:

Before swap:

x value: 10

y value: 20

After swap:

x value: 20

y value: 10

13 . Write a Java program to print the source code .

public class SourcePrint {

private static final long serialVersionUID = 1L;

public void test(){

System.out.println(“Hi I’m test”);

}

public static void main(String[] args) {

new SourcePrint().test();

}

14 . Write a Java program to print Hello without using semicolon .

C Program to print “hello” without semicolon

We can print “hello” or “hello world” or anything else in C without using semicolon. There are various ways to do so:

Using if
Using switch
Using loop etc.

Program 1: Using if statement

Let’s see a simple c example to print “hello world” using if statement and without using semicolon.

#include<stdio.h>
int main()
{
if(printf(“hello world”)){}
return0;
}

Output:

hello world
