public static int secret(int value) {
int prod = 1;
for(int i =1; i <= 3; i++) {
prod = prod * value;
}
return prod;
}
What would be the output of:
System.out.println("First secret call: " + secret(5));
System.out.println("Second secret call: " + (2 * secret(6)));
and what does the method secret do
The output would be 125 and then 432. The method, "secret", cubes the number passed into it.
everything fits in a very small screenshot in two windows... try it, you will see it is fun, like playing lego but with more magic!!!

I would like to put the following to a for loop. How do I do this since we haven't studied arrays yet. My instructor would like me to put the quarters 1-4 to a for loop.
quarter = 1;
interest = principal * quarterlyRate; // item 5
finalAmount = principal + interest;
System.out.printf("%6s%8d%16.2f%30.2f%n", year, quarter, interest, finalAmount);```
Maybe this is what you want:
# looping here
for (int i=0; i<4; i++) {
interest = principal * quarterlyRate; // item 5
finalAmount = principal + interest;
System.out.printf("%6s%8d%16.2f%30.2f%n", year, i, interest, finalAmount);```
}

I have the below one line of code:
variableDoubleValue = ((10*variableDoubleA) + (6.25*variableDoubleB) – (5*variableByteC) + 5);
How can I write it in a Java understandable code?
From what I infer from your question, you want a Java-language based variable declaration and assignment.
Well, if this is the case, then the result will be :-
//public class MathemathicalExpression{
// public static void main(String[] args){
// Double A=some_value,B=some_value,Value=0; considering A,B and Value to be of type Double
// Byte C=some_value; considering C to be of type Byte.
Value = 10 * A + 6.25 * B - 5 * C + 5;
// }
//}

CODE:
for (int i =0; i<=10; i++) {
System.out.println(movieasArrayList.get(i).getID() + " " + movieasArrayList.get(i).getAction());
}
QUESTION:
Change this for-loop to a for-each loop to perform the same task for all Movies (not just first 11).
Any help will be appreciated!!
The for-each loop structure in java goes as follows:
// works with collections and arrays, everything
// that has an iterator
Collection<Object> c = new Collection<Object>();
for (Object i : c) {
// do code
}
For you, this would look like this:
// I don't know what your movieArrayList contains
for (Movie i : movieArrayList) {
System.out.println(i.getId() + " " + i.getAction());
}
Hope this helps!

What is the equivalent Java for this PHP code?
//print string plus/with variable
$mystring = "this is string " .$string
//print sum one + two
$count = $one + $two
//print sum one*two
$count = $one * $two
It should be like :
String mystring= "this is string " + string; // here `string` is aloso String object
/*
* if count ,one and two all of them are int
*/
int count = one + two;
int count = one * two;
But i would suggest to learn basics of java before starting android. As you know php it will not take long to learn java syntax.

i want to store string value in array or in in separate variable using java please short out my problem
Thanks
String a1,a2,a3;
while (resultSet.next()) {
isFound=true;
jLabel2.setText("hello");
String s1=resultSet.getString("Court_Num");
System.out.println(s1);
output s1=: 101
102
103
Desired out put: a1=101
a2=102
a3=103
Your question is confusing I think for 1st record you want a1=101 for 2nd a2=102 etc
int i=1;
while (resultSet.next()) {
if(i==1)
{String s1=resultSet.getString("Court_Num");
System.out.println(a1+"="+s1);}
if(i==2)
{String s1=resultSet.getString("Court_Num");
System.out.println(a2+"="+s1);}
if(i==3)
{String s1=resultSet.getString("Court_Num");
System.out.println(a3+"="+s1);}
i++
The title mentioned using an array. That would look something like this:
String[] a = new String[3];
for(int i=0; resultSet.next(); i++) {
a[i] = resultSet.getString("Court_Num");
System.out.println("a" + i + "=" + a[i]);
}
