Arrays in Java

What is an Array?

An array stores multiple values of the same type in one variable, accessed by index (starting at 0).

Create and Loop

int[] marks = {88, 92, 79, 95};
int sum = 0;
for (int i = 0; i < marks.length; i++) {
    sum += marks[i];
}
System.out.println("Total: " + sum);
System.out.println("First: " + marks[0]);

Total: 354 First: 88

For-Each Loop

for (int m : marks) {
    System.out.print(m + " ");
}

88 92 79 95

Summary

Arrays hold many same-type values; index starts at 0.
.length gives size; for-each loops easily over items.

Array क्या है?

Array एक ही type की कई values एक variable में रखता है, index से access (0 से शुरू)।

बनाएं और Loop करें

int[] marks = {88, 92, 79, 95};
int sum = 0;
for (int i = 0; i < marks.length; i++) {
    sum += marks[i];
}
System.out.println("Total: " + sum);
System.out.println("First: " + marks[0]);

Total: 354 First: 88

For-Each Loop

for (int m : marks) {
    System.out.print(m + " ");
}

88 92 79 95

सारांश

Arrays एक ही type की कई values रखते हैं; index 0 से।
.length size देता है; for-each items पर आसानी से loop करता है।
