[CLT][Thread:  0x00286c58] at java.lang.Runtime.gc(Native Method)
[CLT][Thread:  0x00286c58] at java.lang.System.gc(System.java:737)

[CLT][Thread:  0x00286c58] at Sample.main(Sample.java:5)

If the number of characters in a line exceeds the specified number of bytes, the characters after at are deleted in order from left to right, until the number of characters in the line is equal to the specified number of bytes. In the fourth line of the above output example, the characters "Sa" have been deleted from Sample, and only mple appears.
