I'm a total beginner to java and need help writing this nested for loop. This is the desired output.
2 3 5
5 10 26
11 31 131
23 94 656
I understand that the increment is 2 times the first number + 1, but I don't understand how to create the loop for it.
public static void main(String[] args) {
for(int i = 2; i <= 5; i++) {
for(int j = i; j <= i; j++) {
System.out.print(j+(i*j));
}
System.out.println();
}
}
Question is so simple it consists of two things read the pattern and use the appropriate loop statements in java to achieve this. Printing them is another task which is not difficult.
@Jonathan your pattern is right but your algorithm is incorrect.
I'm not giving you perfect solution but you have to use proper loop statement to make it efficient. I'm here giving you a thought so that you can think in this way..hope you get it.
public static void main(String[] args) {
/* 2 3 5
5 10 26
11 31 131
23 94 656
*/
int two = 2;
int three = 3;
int five = 5;
int i=0;
//use do-while to print 2 3 5
do{
System.out.println(two +" "+ three +" "+five);
two=two*2+1; // apply math pattern
three= three*3+1;
five= five*5+1;
i++;
}while(i<4);;
}
Please try the following code (I have tested the code, the output is exactly the same as yours):
public static void main(String args[]) {
int[][] results = new int[4][3];
results[0][0] = 2;
results[0][1] = 3;
results[0][2] = 5;
for (int i = 1; i < results.length; i++) {
for (int j = 0; j < results[0].length; j++) {
results[i][j] = results[i - 1][j] * results[0][j] + 1;
}
}
for (int i = 0; i < results.length; i++) {
for (int j = 0; j < results[0].length; j++) {
System.out.print(results[i][j] + "\t");
}
System.out.println();
}
}
