public class Test
{
public static void main(String args[])
{
double[] myList={1.9,2.9,3.4,3.5};
for(int i=0;i<myList.length;i++)
{
System.out.print(myList[i]+" ");
}
System.out.println();
double total=0;
for(int i=0;i<myList.length;i++)
{
total+=myList[i];
}
System.out.println("Total is "+total);

//Taken 1 variable of name max and assign value of first element of given array myList [] to it ie 1.9  

double max=myList[0];   
//Taken one loop which will traversing from one location to another
//i=0 to point first element of myList[] array n it will visit all the locations of given erray until it gets last value
  
for(int i=0;i<myList.length;i++)
{
//Inside loop we have taken if else structure to get max value
//Here we are comparing value of array and the value of max ie already assigned before the loop ie myList[0]=1.9
if(myList[i]>max)
{
//For i=0 myList[0] has value 1.9 and comparing it with max variable value ie 1.9 so it will not satisfy the condition so //it will go for next iteration
//so for i=0 ,max=1.9
//for i=1, myList[1] has value 2.9 and max has 1.9 so it will satisfy the if condtion ie value of myList[1]>max ie 2.9>1.9
//it will come down and assign 2.9 to max and remove previous value ie 1.9 so max got new value ie 2.9
//for i=1, max=2.9
//for i=2, still loop is on so it will go for next value ie i=2 here myList[2]=3.4 so again it will satisfy the condition and assign 3.4 to max and remove/override previous value ie 2.9
//for i=2, max=3.4
//for i=3, now max has value 3.4 and myList has value 3.5 again it will satisfy the condition of if and assign value of myList[2] ie 3.5 to max
//so at this time max has a value 3.5
//again value of i will increase by1 but as it becomes i=4 then it will not satisfy the condition of for so it will come out from the loop
// so at last max is holding value 3.5
max=myList[i];
}
}
//as print the statement you will get the value of max ie 3.5
System.out.println("Max is "+max);
}
}
