//getting arrayindexoutofbound exception
5 years ago
int i[]={10,20,3,2,4};
int j[]={5,2,15,16,18};

need a new array which will be having elements based on if 'array i' will be compared to 'array j'

Ex:
10 will be compared against 'array j'and and so on ,Only unmatched elements index will be the elements of new array
for 10,20,3,4 will be unmatched so their indexes will be printing into another array

output :
{0 1 2 4}

please help me solve this

yes,that is the problem

!found what is the significance of this and how its substituting the 'If' statement

public class ArrayNumberCheck
{
private static boolean checkInArray(int checkNum, int[] myArray)
{

boolean found = false;

for (int i = 0; !found && (i < myArray.length); i++) // how its behaving ?
{

found = (myArray[i] == checkNum);
}

return found;
}


public static void main(String[] args)
{
int[] arr = {10,5,15,20,25,200};
int checkNum = 2;

boolean valid = ArrayNumberCheck.checkInArray(checkNum,arr);

if (valid)
{

System.out.print("Value in Array");

}

else

{

System.out.print("Value Not In Array");

}


//System.out.print("Number exists in array");
}
}

Please help me understand this why this is not compiled??

Why re-initializing the static variable in separate line is invalid??

public class Test {

static int a;
a =10; //why its invalid

public static void main(String[] arg){
System.out.print(a);
}
}


compilation error: identifier expected why initializing a=10; is not valid whereas static int a=10; is working fine
