Labeled Statement

LabeledStmt Entity

In Java, a labeled statement allows you to assign an identifier (label) to a specific block of code or statement. Labels are most commonly used with break and continue statements to control the flow of nested loops or blocks. When using a labeled statement, you place the label name followed by a colon (:) before the statement or block you want to label. This is particularly useful when you need to break out of or continue a specific outer loop from within a nested loop structure.

Example

outer: // Label for the outer loop
for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
        if (i == 1 && j == 1) {
            break outer; // Breaks out of the outer loop
        }
        System.out.println("i = " + i + ", j = " + j);
    }
}

// Example with continue and label
search:
for (int i = 0; i < array.length; i++) {
    for (int j = 0; j < array[i].length; j++) {
        if (array[i][j] == -1) {
            continue search; // Skips to the next iteration of outer loop
        }
        // Process array[i][j]
    }
}
