It's a label, though look at the following example:

int a = 0; int b = 0 while (a<10){ firstLoop: a++; while(true){ b++ if(b>10){ break firstLoop; } } }

When b>10 the execution flow goes to the outer loop.

It's a label, though look at the following example:

int a = 0; int b = 0 while (a<10){ firstLoop: a++; while(true){ b++ if(b>10){ break firstLoop; } } }

When b>10 the execution flow goes to the outer loop

It's a label, though look at the following example:

int a = 0; int b = 0 while (a<10){ firstLoop: a++; while(true){ b++ if(b>10){ break firstLoop; } } }
