Condition in for loop what it means ?

Question

int[][] abcd;
for ( int[] abc : abcd){
....
....
...}

Answer 1

for( int x = 0; x < 5; x++){
System.out.println(x);
)

the ( x < 5 ) is a condition. It means that when x is smaller run the loop.

It is like an if statement's condition:
if(true){
System.out.println(true);
}
