Nested for loop with examples

I can't understand how the flow of nested loops are when I saw several * print programs

for (int i = 1; i <= 4; i++) { for (int k = 1; k <= 3; k++) { // some code } } i, k values on following iterations: i = 1, k = 1 i = 1, k = 2 i = 1, k = 3 i = 2, k = 1 i = 2, k = 2 i = 2, k = 3 i = 3, k = 1 i = 3, k = 2 i = 3, k = 3 i = 4, k = 1 i = 4, k = 2 i = 4, k = 3 In other words, whole inner loop will be executed for each iteration of outer loop. If outer loop runs n times, inner loop runs m times, then code in the inner loop will be executed n*m times.

Perhaps, due to lack of the basic programming knowledge: syntax, terms, keywords. I personally can not explain it in other words in a simple way. My advice for you is to finish your Java course on SoloLearn at first. Try to run this code, maybe it helps: for (int i = 1; i <= 4; i++) { for (int k = 1; k <= 3; k++) { System.out.print("i = " + i); // prints out i value System.out.println(", k = " + k); //prints out k value } }
